Projected goals against:
If you missed the explaination for these calculations the first time around, I basically just take the average of the team's goals conceded and their opponent's goals scored based on who is home and away. Those highlighted in red are the gameweeks where the team is predicted to concede less than one goal and are high chance of a clean sheet.
Projected goals for:
Basically, the same calculation as above, only calculated for the team's goals scored. The cells highlighted in red are games where the team is projected to score more than 1.5 goals.

Goals for/against home/away
We are now at a point in the season where every team has played at least 5 games at home at 5 away. That is the point where I'm going to start using data based only on this season to project goals scored and conceded. I'll share the next 5-week projections in another post, but this one will just show some raw data for each team on how many goals they score and concede per game both home and away. I've ranked them from best to worst:

Week 15: fail to prepare, prepare to fail.
The double-gameweek bacchanalia of week 11 is over and our
rosters are locked for the morning-after bloody mary of week 12’s Philly/LA
double. Weeks 13 and 14 aren’t anything special but weeks 15 and 16 loom on the
horizon. If you happen to still have your wildcard, use it between weeks 15 and
16 and take advantage of good matchups between now and then. For the rest of us
that used our wildcard early (week 3 for me), we need to start planning NOW.
Week 15 has 9 teams without a game and week 16 has 5 teams without a game and 4
teams with a double. Oh yeah, then there's a bunch of players gone for international duty to boot.
Week 15 players:
·
Chicago
(vs. Portland)
·
Columbus
(at Philly)
·
DC
(at New England)
·
LA
(at RSL)
·
New
England (vs. DC)
·
Philly
(vs. Columbus)
·
Portland
(at Chicago)
·
RSL
(vs. LA)
·
Seattle
(vs. Vancouver)
·
Vancouver
(at Seattle)
Week 16 feast:
·
Colorado (vs. San Jose and at Chicago)
·
Montreal (at Columbus and vs. Houston)
·
Portland (vs. Dallas and at LA)
·
Vancouver (vs. New England and vs. Chivas)
Week 16 famine:
·
New York
·
Philly
·
RSL
·
Seattle
·
SKC
So, what teams do we target to bring in and when do we do
it?
Targets to transfer in before week 13 deadline:
RSL and New England – both teams have 3 home
games in a row in weeks 13, 14, and 15. I like New England’s defense as the
best target for transfers this week as they are projected to keep 2 clean
sheets out of 3 based on this season’s goals scored/conceded home and away for
them and their opponents. I plan to double-up on New England defenders. RSL’s
prospects on defense don’t look as good, with their only projected clean sheet
coming in week 13. On the other side of the ball, RSL players are more
attractive and are projected to score more goals than anyone over the coming 3
weeks (tied with LA and Columbus). RSL do have a blank in week 16, so limit
yourself to a maximum of 2 RSL players. If you don’t like either RSL or the
Revs, LA is where you want to invest
as they don’t have a blank week during this stretch and project decent enough
returns.
Targets to transfer in before week 14 deadline:
RSL and New England players are still fine
targets here. However, the best targets at this point are Columbus attackers. Columbus have two home games surrounding an
away trip to face a leaky Philly defense. Seattle
are projected to score the most goals in weeks 14 and 15 combined and are
projected to keep a clean sheet in week 15 so they are worth a look - beware of
their blank in week 16. Aside from that, there really aren’t many favorable
matchups. You could look at Vancouver who
are the only team who play 4 games during weeks 14-16 (two home games in week
16 look tempting). My plan for week 14 is to make just a single transfer and
roll the other over into week 15. There aren’t many players I’m excited about
in week 14 who play in week 15, and it also allows us the flexibility to shift
money around in week 15 and helps avoid potential injury/suspension issues.
Targets to transfer in before week 15 deadline:
At this point, a lot depends on who you have and how you’re
set up for week 16. Portland and Vancouver are the only two teams to
play in week 15 and have a double in week 16. Vancouver does have a blank in
week 17, so I’m not crazy about them as transfer targets after this week. Portland
and Colorado are the teams with doubles in 16 and no blank in 17, so Portland
players are where I’d look to first – might even triple up on Timbers by week
16. Columbus is projected to score
the most goals during this week and don’t have a blank in 16 or 17 – not the
most exciting picks going forward, but good enough to fill some roster slots if
needed for week 15. If you want to start building again for after week 15, then
LA are your guys as they have no blanks
and project well going forward.
Top individual transfer targets by week:
Week 13: Morales, Goncalves, Schuler, Farrell, Shuttleworth,
Donovan, Keane
Week 14: Higuain, Rosales, Morales, Goncalves, Farrell,
Shuttleworth, Oduro
Week 15: Wallace, Valeri, W. Johnson, Higuain, Oduro,
Donovan, Keane
My plan:
Week 13: Ashe to Farrell and O. Gonzalez to Goncalves
Week 14: R. Johnson to Oduro
Week 15: Holgersson to Wallace, Hedges to Lee, save third
transfer to bring in a player with a double week 16
My spring coaching season officially ends this weekend, so expect a couple posts over the next couple weeks as I will suddenly have free-time on my hands.

new fantasy resources
a couple more useful resources have cropped up in the last few days that can help us maximize our decisions.
corners, PKs, and free-kicks
this is far more comprehensive than my page (now deleted)
fantasy overlord
this is a mathematical projection tool that was developed from the same math behind a tool that picked the fantasy team over the season and placed in the top 500 for EPL fantasy. I have a lot of reservations about how it translates to MLS, knowing how much a team can change from year to year. That said, I think their team projections are likely to be more valuable than what I have used for my projected goals scored and projected goals conceded. The player projections are useful for players that played a lot of minutes last year, but are useless for players who missed time due to injury or came in mid-season (bernardez, ferreira, zakuani, higuain, o. gonzalez, etc.). this tool should improve it's predictive ability as more of this season's data is entered.

Which stats REALLY matter for a position?
I have been wondering for a while which stats are the most important to target and what type of players are most likely to produce high quantities of those stats. My main purpose for this is to find individual players who underperformed for us in fantasy last season that might be able to give us better returns this season if they have similar performances. In other words, what players got screwed over last season because their teammates didn't live up to average?
What I've done is look at the correlation between PP90 and every statistic that provides fantasy points and a couple that don't provide points such as shot conversion percentage and key pass conversion percentage. I've done this on a positional basis only, so we know which stats are most important for each position.
Defenders:
Defenders are the most inconsistent group of players in terms of finding a stat that highly correlates with PP90. CBI had the highest correlation at 0.34. Goals and assists follow with correlations of 0.29 and 0.28 respectively. The big shocker, is that a team's clean sheets has a surprisingly low level of correlation - a mere 0.19 - with a defender's PP90.
So, what does this mean? It's tough to draw any firm conclusions about what defenders we should choose. Since CBI and goals are the two stats with the highest correlation with PP90, I am inclined to say that we want to pick center backs who get forward on set-pieces. This is fairly accurately reflected in the players found at the top of my defender projections. We see center backs like Collin, Bernardez, Ianni, Taylor, Berry, Olave, and McDonald all feature as good targets according to my PP90 projections.
Midfielders:
There are a couple stats with much higher correlation with PP90 for our midfielders. Assists correlate with midfielder PP90 at a strong 0.77. However, there are several other stats that correlate at better than 0.5: key passes (0.72), goals (0.68), and crosses (0.62).
There's a couple things to take away from this. First, is the reason there is such high correlation for several statistics is that there are some midfielders (pretty much every defensive midfielder in the league) who simply don't rack up any of the above categories. Even with the added defensive points for CBI and recoveries available, defensive midfielders simply don't score enough of them to make them viable alternatives to their attacking counterparts.
We know we want attacking midfielders, but do we want wingers or central midfielders? Both versions of an attacking midfielder has about equal opportunity for goals, assists, and key passes. It isn't until we get to the fourth most highly correlated statistic where we find our answer. A decently high correlation with crosses and PP90 means we want wingers. Zusi, Rosales, Davis, Pontius, Chaves - all are in the top level of my midfielder projections and all are wingers. It should be noted that there are several central playmakers who also rank high in my projections (Morales, Ferreira, DeRosario) who take freekicks, corners, and/or PKs and are also valid targets.
Forwards:
Surprise, surprise, goals is the stat that best correlates with PP90 for forwards at 0.77. Assists (0.69) and key passes (0.64) also had high levels of correlation with PP90.
In our forwards, we are looking for goalscorers. I'm sure everyone who has even heard the term "fantasy soccer" could have told you that. However, I was surprised at how highly correlated both assists and key passes were with PP90 which gives me second thought about choosing guys who are poachers (Bengston, Bruin, Cooper and to a lesser extent, Wondolowski) instead of more well-rounded players (Higuain, Henry, Keane).

Alternate method for finding value
This time instead of looking at how much overvalued or undervalued a player is, I looked to see how much value they give in terms of projected season points per $million spent (PPM). Generally, this returns the same players near the top of the rankings as my previous method. This might be a simpler way for people to understand exactly how much return they can expect from their investment.
Here's the takeaways:
Defenders
Midfielders
Forwards
Here's the takeaways:
- The best use of these charts is to find cheap players who have the potential to give us decent returns when they are called upon to come off the bench.
- Another use for these charts is to find the expensive players who offer a decent return on investment.
- Defenders tend to have a higher PPM than midfielders who have a higher PPM than forwards.
- It looks as though there are several cheap options in defense that have a good PPM. This leads me to believe this is the area we should look to save a bit of cash for some attackers with lower PPM but higher season points. Look to pick up at least two of Woolard, McCarthy*, Tierney*, Korb*, Hedges, Hurtado, and Parke.

Finding players who are undervalued: Part 4 - forwards
And finally we look at pricing inefficiencies of our forwards. Again, I have grouped the top couple prices into a single "elite" bracket. For those of you who are contributors to r/mls, this highlights exactly why I was trying to convince people that Henry was a better choice for MVP than Wondo... but that's a different blog post. There has been a lot of movement for these players' supporting players this offseason with the exception of Wondo. Henry lost Cooper to Dallas, Saborio lost Espindola to New York, Johnson lost Montero to the allure of Libertadores soccer, and Keane lost Donovan to an existential crisis. It will be difficult to say exactly how all these moves will affect the elite strikers, but my guess is every one of them has a worst season than last except for Johnson and Saborio. That doesn't mean they're not worth owning, however, and we have to go with one or two of them simply for good options to captain when they have easy gameweeks.
The players we want to have that breakout season that can make our friends wonder, "how the hell did you know he was going to score so many goals this season!?" I actually made a bold prediction that Arrieta is going to win the golden boot this year so long as Higuain remains healthy. I would still pick Higuain and try to find somewhere else to save the money. Ryan Johnson and Juan Agudelo are two players I think will overperform these predictions simply due to changes in playing style and new coaches. At this point, Estrada looks to be Seattle's second striker, but I wouldn't be surprised to see Martinez eat some of those minutes.
Again, the budget options here are not locked-in starters. MacDonald is the only one who seems to be the first choice for their team. Mwanga might be with the injury to Dike and Oduro has seen time with the first squad in the preseason for Columbus. If Gordon does end up being a starter (because of running a 4-3-3 or Wondolowski dropping to a midfield role) he becomes the best value in the entire game. It will be tough to be as efficient as last season, but still has plenty of room to deliver adequate returns for his price.
Higuain - the most undervalued player in the entire game who is guaranteed to start (Gordon ranks above him, but is not a locked-in starter). Higuain - the player projected to score the most points out of anyone in the entire game at any position. Higuain - the guy who only has one home game (against San Jose nonetheless) in the first five gameweeks. No player has been in and out of my lineup more. He's only owned by a mere 10% at the time of writing, so has potential for significant price rise if he starts hot and not much danger of significant price fall if he doesn't.
Not quite elite options here, but still pricy enough to make it feel like they should be producing more than these guys did last season. Espindola is an interesting option for me. Assuming he'll be playing a similar role as Cooper did last season, he should get plenty of quality chances, though his historical shot conversion rate is lower. Hassli is another player who I think will greatly benefit from his transfer to Dallas.
