Comparing 2014 Vegas Projections to Estimated Wins

March 28, 2014 Vegas

Three weeks ago, Vegas released the first set of 2014 win totals for all 32 teams. I immediately wondered how those win totals compare to the estimated wins I created based on 2013 DVOA ratings. I tweeted a request for someone to write such an article, and Warren Sharp (@SharpFootball) was kind enough to oblige. […]

Does Vegas undervalue bad teams and overvalue good teams?

March 8, 2014 History

The prevailing view is that Vegas is an example of an efficient market. If there were obvious trends that oddsmakers ignored, it would be easy for people to make money gambling on football, and we know that’s not the case. But I thought it would be interesting to investigate some claims I’ve heard over the […]

Why is the Over/Under So Low In Super Bowl XLVIII?

February 2, 2014 Vegas

The Over/Under for Super Bowl XLVIII was just 48 points for most of the last week, although it went up to 48.5 on Thursday and may be at 49 by kickoff. In any event, such a low number should strike Broncos fans as really odd, since the average over/under in the team’s first 18 games […]

How Likely Or Unlikely Was Each Super Bowl Winner Since 1978

January 25, 2014 Super Bowl

Earlier this week, I looked at how likely or unlikely the playoffs were in each of the last 25 seasons. Today, we look at each Super Bowl winner since 1978, and calculate their odds of winning each playoff game, and by extension, how likely (or unlikely) it was that that team wound up winning the […]

The 2013 Playoffs Were Not Very Random

January 22, 2014 Vegas

In September 2012, Neil wrote that the NFL playoffs had become more random. And that was three months before Joe Flacco turned into Joe Montana. This year, however, feels like one of the least random playoffs in recent memory. And there’s a good reason for that: it is. If you know the points spread for […]

The Patriots are 10-3 But Just 6-7 Against the Spread

December 13, 2013 Checkdowns

If you look at the Patriots’ PFR page, you’ll see that the Patriots are a 10-3team that’s played like an 8-5 team that has a 6-7 record against the spread. I wondered how often a team with such a good record was below average against the spread. The answer: pretty frequently. Which I suppose isn’t […]

New York Times: Post-Week 3, 2013

September 25, 2013 Current Events

This week at the New York Times, I examine the disappointing San Francisco 49ers. From the moment Coach Jim Harbaugh arrived in San Francisco in 2011, the 49ers have been one of the N.F.L.’s best teams. In Harbaugh’s first two seasons, the 49ers ranked third in combined wins (24) and points differential (275), trailing only […]

Favored to win or lose every game?

September 22, 2013 Vegas

On Monday and Tuesday, I looked at the teams that had the longest streaks as either a favorite or an underdog. In the comments, James asked if I could put together a list of teams that were favored to win or lose every game in a single season. Six teams — the ’98 Broncos, ’95 […]

Longest streaks as an underdog

September 17, 2013 Vegas

Yesterday, I looked at the longest streaks as a favorite. The ’99 to ’02 Rams were the record holder, as the team was favored in an astounding 57 consecutive games. Unfortunately for the franchise, things weren’t so great in the post-Kurt Warner era. In fact, five years after that streak ended, the Rams started a […]

Longest streaks as a favorite

September 16, 2013 Vegas

On its own, this week five game against San Francisco doesn’t stand out as anything special. The 0-4 Rams were traveling to San Francisco with Jamie Martin at quarterback, who led the team to just 10 points the previous week in Dallas after Kurt Warner broke his pinky finger. The 49ers were coming off of […]

Buffalo Bills website complains about team’s schedule

June 24, 2013 Random Perspective On

Chris Brown of is not happy with the way the Bills’ schedule shakes out. Again. Last year, this is what Brown wrote after examining the 2012 schedule: After playing what is expected to be a physical contest with the 49ers in San Francisco in Week 5 [Chase: In retrospect, not that physical], the Bills […]

Super Bowl XLVII Prop Bets

I don’t advocate betting on football games and neither does Football Perspective.

Now that the Super Bowl matchup is set, I thought I’d start the two-week period with some Super Bow history. The table below lists some information from each of the first 46 Super Bowls. With Joe Flacco and Colin Kaepernick facing off, that ends five-year streak where at least one of the two quarterbacks in […]

Oregon, Kansas State, and Notre Dame look undervalued this weekend

Unfortunately, the two biggest games of the day — Alabama/LSU and Oregon/USC — will compete for the eyeballs of the nation. The Ducks and Trojans kick off at 7PM on the East Coast, with the Crimson Tide stealing our […]

There is only a 10% chance Oregon, Kansas State, and Notre Dame all go undefeated

October 28, 2012 College

Neil once pointed out, that you can approximate a team’s odds of winning a game by using the point spread and the following formula: p(W) = 1 – (1-NORMDIST(0.5,SPREAD,13.86,TRUE))+0.5*(NORMDIST(0.5,SPREAD,13.86,TRUE)-NORMDIST(-0.5,SPREAD,13.86,TRUE)) For college football games, there is research by Wayne Winston and Jeff Sagarin that the standard deviation in the above formula should be 16 instead of […]

We don’t know anything and we never will

October 9, 2012 History

Five weeks in, you start to hear NFL experts trade their preseason overconfidence for regular season overconfidence. It’s tempting to fall into the trap thinking that with over a quarter of the season in the books, now we have an idea of how the rest of the regular season will unfold. It’s tempting, but it’s […]

How predictive is 4th quarter play?

October 8, 2012 Statistics

Last week, Neil had a fascinating post on how each team’s win probability has varied by quarter over the last 35 years. The 2004 Pittsburgh Steelers were the poster child for wins added during the 4th quarter and overtime. Pittsburgh went 15-1, which means they exceeded the league average by 7 wins (the average team, […]
