Win Probabilities and Expected Wins 2007 - Week 17

The following table lists the probabilities that the home team would win each game given the rushing averages, passing averages (includes sack yards lost and sacks as pass attempts), sack rates, third down conversion rates, penalty yards, and interception and fumble rates (by number of completions and rushing plays) for both teams. A logistic regression model trained on 1996-2006 data computes the probabilities. The final score margin is Home team points - Away team points. The sum of these probabilities of victory form the expected win totals in the second table after the jump.

Now that the 2007 regular season has drawn to a close, we can now take a look at teams expected to improve/decline in 2008 based on these numbers. (after the jump)

Teams that "should have" won but didn't
New York Giants (vs. Patriots), Win Prob = 65.5888% The Giants averaged 4.2 yards per carry. The Patriots averaged 1.7 ypc. The Giants averaged 7.2 yards per pass. The Patriots averaged 5.7 ypp.
Tampa Bay Bucs (vs. Panthers), Win Prob = 58.6529% Carolina had two fumbles, only one of which was lost.
Jacksonville Jaguars (@ Texans), Win Prob = 62.5203% Jacksonville averaged 7.0 yards per pass versus 6.3 for the Texans, and they were better on third down. Houston also threw one pick against one Jags fumble. Houston also ran only 19 pass plays, inflating the interception and sack rates.

Power Rankings 2007 Week 16

The power rankings for this site were developed in this article. The idea behind them is simple: if each team played one home game and one away game against every other team in the league, who would be the most successful?

The power rankings use logistic regression to predict the probability of winning. The score you see along with the rankings is the expected win total over a 16-game season based on the expected winning percentages over the 62 games (i.e. the sum of those probabilities).

The Value of Homefield Advantage 2007 Week 16

One of the things I've learned in my football research is that the value of home-field advantage varies pretty widely from year to year, especially with interconference games. Because prediction systems tend to have a big bias towards the home team, this can have a large impact on accuracy. So throughout the season, I'll be keeping track of home team winning percentage and average final score margin (home team points - away team points) for interconference, interdivision, and intradivision matchups. If you're interested in that sort of thing, it can help you with betting on the spread (hint).

All Games
Home Team Win %: 56.6667%
Avg. Final Score Margin: 2.7000

Interconference
Home Team Win %: 65.0000%
Avg. Final Score Margin: 5.6000

Win Probabilities and Expected Wins 2007 - Week 16

The following table lists the probabilities that the home team would win each game given the rushing averages, passing averages (includes sack yards lost and sacks as pass attempts), sack rates, third down conversion rates, penalty yards, and interception and fumble rates (by number of completions and rushing plays) for both teams. A logistic regression model trained on 1996-2006 data computes the probabilities. The final score margin is Home team points - Away team points. The sum of these probabilities of victory form the expected win totals in the second table after the jump. The tables will be updated as more box scores come in.

Teams that should have won but didn't
Tampa Bay Buccaneers (@ 49ers), Win Prob = 77.8473% Though Tampa Bay fumbled three times and gave up 4 sacks, they passed over twice as much as the 49ers and ran 35 more plays, lowering their sack, fumble, and interception rates. They gained 6.6 yards per pass versus 4.5. Each threw a pick, and Tampa Bay was more efficient on third downs.
Cleveland Browns (@ Bengals), Win Prob = 65.8147% Cleveland was slightly more efficient running but less efficient passing. Each team had two fumbles, but Cleveland threw four interceptions versus Cincinnati's two. Again, total number of plays comes into effect, as the Browns ran 49 pass plays while the Bengals ran 21.
Kansas City Chiefs (@ Lions), Win Prob = 75.2938% Kansas City ran 3 times as many pass plays as the Lions, averaging 6.6 yards per pass while the Lions managed only 5.5 ypp. Each team threw a pick, but the Lions' pick carries a much heavier weight because they threw the ball only 16 times.
Atlanta Falcons (@ Cardinals), Win Prob = 52.9437% Atlanta gained 4.4 yards per carry, while Arizona could gain only 2.8 ypc. They were about equal in terms of passing and third downs, and each team had a turnover. Atlanta fared slightly worse in terms of penalties and sack rates. These teams played about equally well, which is indicated by the probability and the result (an overtime win by a field goal).

Predictions 2007 Week 16 and Accuracy Report

The predictions are based on yards per play on rushing and passing plays (sacks and sack yards included), sack rates, third down conversion rates, penalty yards per game, and fumble and interception rates. The models are trained on the 1996-2006 seasons. Linear regression predicts the final score margin (home team points - away team points). Logistic regression estimates the probability that the home team will win.

Power Rankings 2007 Week 15

The power rankings for this site were developed in this article. The idea behind them is simple: if each team played one home game and one away game against every other team in the league, who would be the most successful?

The power rankings use logistic regression to predict the probability of winning. The score you see along with the rankings is the expected win total over a 16-game season based on the expected winning percentages over the 62 games (i.e. the sum of those probabilities).
