Week 1 - Week 2
Hope everyone's having a nice weekend and looking forward to Week 2. I'll try to get this up earlier in the week in the future, and for simplicity's sake, I'm going to try to streamline the flow as much as possible.
Every week, I'll summarize top five against-the-spread value plays and top five moneyline value plays. Both are based on teams' aggregate probabilities to cover or win across the 50+ NFL prediction models on The Prediction Tracker. I apply those probabilities to Westgate odds to produce expected values. I'll also post an updated summary of NFL futures values for all 32 NFL teams. In this case, I'm applying teams' average probabilities to win the division, conference, and Super Bowl across ESPN FPI, Football Outsiders, and Massey-Peabody Analytics to their Westgate futures odds to produce expected values. I am not suggesting that you bet these. In fact, the expected value of $100 on almost all of the games and futures below is less than $100. Good luck trying to win when the odds are literally stacked against you. Nevertheless, I find it interesting to see where the value potentially lies — particularly in NFL futures. Please revisit Week 1 for more information on methodology.
I. Against the Spread — Top 5 Value in Week 2
1. Tennessee +3.0 vs. Houston (even) — 70% chance to cover — $70 expected value on a $100 bet 2. Dallas -3.0 vs. N.Y. Giants (-110) — 62% chance to cover — $56 expected value on a $100 bet 3. New Orleans -9.5 vs. Cleveland (-110) — 59.3% chance to cover — $53.9 expected value on a $100 bet 4. Minnesota -0.0 at Green Bay (-110) — 59.2% chance to cover — $53.9 expected value on a $100 bet 5. Baltimore -0.0 at Cincinnati (-110) — 58.9% chance to cover — $53.6 expected value on a $100 bet For the second week in a row, the team playing the Houston Texans has the highest expected value against the spread, and the teams playing the N.Y. Giants and Cleveland Browns aren't far behind. That suggests that oddsmakers and the public like the Texans, Giants, and Browns more than the models do, That makes sense given that the models often look to last season as a baseline, when the Texans were injured, the Giants were bad, and the Browns were horrific. We'll see how things shake out in Week 2. Baltimore already lost at Cincinnati on Thursday night. Top five value plays were 4-1 in Week 1 (+390). LAST WEEK: 4-1 (+390) 65%+ COVERS: 2-0 (+200) 60%+ COVERS: 2-1-1 (+80)
II. Money Line — Top 5 Value in Week 2
1. Arizona: +750 at L.A. Rams — 23% chance to win — $174 expected value on a $100 bet 2 Buffalo: +280 vs. L.A. Chargers — 38% chance to win — $106 expected value on a $100 bet 3. Tennessee: +145 vs. Houston — 62% chance to win — $91 expected value on a $100 bet 4. Oakland: +240 at Denver — 38% chance to win — $90 expected value on a $100 bet 5. Kansas City: +215 at Pittsburgh — 41% chance to win — $88 expected value on a $100 bet These plays went 2-3 in Week 1, but because the list included underdogs (mostly heavy underdogs), that sub-.500 outcome would have generated meaningful profit. The Jets won as +250 underdogs at Detroit and the Bucs won as +375 underdogs at New Orleans. The Bears almost won (+260) at Green Bay, too. The plays listed here each week will almost certainly be underdogs. That's because the models think certain games are a bit more balanced than high moneyline odds imply. Check out Arizona for example. At +750, the odds suggest that the Cardinals have a 12% chance to win at the Rams, whereas the models suggest a 23% chance. A 23% chance to win $750 on a $100 wager equates to an expected value of $174. LAST WEEK: 2-3 (+325)
III. Searching for Value in NFL Futures Bets
When reviewing the table below, remember that the expected values listed are only as good as your faith in the probabilities that produce them. For example, if you think Washington really has a 3.0% chance to win the Super Bowl, then there is good value to be had at +5000 (50 to 1). But if you instead think Washington has a 2.0% chance at the Lombardi Trophy, you should view them as fairly priced at +5000. All this really does is compare the models' average probability of a certain event to the probability implied by Westgate's current odds. When the models' average probability is higher that the odds-implied probability, the expected value of a $100 wager will be greater than $100. (They are very few such bets.) Good value doesn't mean an event is likely. It just means you think it's more likely than the odds suggest. After last week's performance, the models believe the Jets have a 20% to win the AFC East, whereas New York's +1000 odds suggest a 9% chance. Value? Depends what you believe. Same logic for everything else. 
Note: Westgate did not have NFC North odds or a Vikings-Packers line as of September 15. I used 5dimes for those this week instead.
