The Buffalo Bills are still in the playoff hunt despite not being a very good team. The Bills have been outscored by 63 points so far this year, but have an 8-7 record. They’ve lost two games by 30+ points and two more by 20+ points, but a 5-2 record in one-score games has Buffalo still in the playoff hunt (the Bills are in with a win in week 17 and either a Ravens loss or losses by both the Titans and Chargers).

The Carolina Panthers are 8-1 in one-score games, the best record in the NFL. Carolina may be a very good team, but the Panthers are just 3-3 in games decided by more than 8 points. Carolina has a Pythagenpat winning percentage of 0.592, which is more in line with a 9-6 team than an 11-4 team.

The table below shows the Pythagenpat winning percentages for each team this season. The Bills and Panthers have exceeded “expectations” by the largest amount this year when it comes to actual winning percentage vs. Pythagenpat winning percentage. The biggest underachievers? The Browns, Bucs, Jaguars, and Chargers. [continue reading…]

The Philadelphia Eagles are 10-1 for the fourth time in franchise history. The Eagles have never started a season 11-0, so this season makes the short list for best start in franchise history.

In 1948, behind head coach Greasy Neale, QB Tommy Thompson, and future HOFers RB Steve Van Buren and WR Pete Pihos, and RB Bosh Pritchard, the Eagles went 9-2-1 and won the NFL title.  In 1949, the Eagles brought back Neale, Thompson, Van Buren, Pihos, and Pritchard, and had similar success.  The team lost to the Bears in week 4 but finished the regular season with a sparkling 11-1 record. Philadelphia repeated as champions, defeating the Rams 14-0 in the NFL title game.

In 1980, the Eagles lost to the Cardinals in week 4, but started the season 11-1 before finishing 12-4 and winning the NFC.  The head coach was Dick Vermeil, the QB was Ron Jaworski, and while RB Wilbert Montgomery and WR Harold Carmichael were the stars on offense, Philadelphia sported a dominant defense that ranked 1st in points allowed, and 2nd in rushing yards allowed, net yards per pass attempt allowed, and rushing yards allowed.  Alas, despite being 3-point favorites, the Eagles lost in the Super Bowl to the Raiders.

The 2004 Eagles was the best Philadelphia team of the modern era.  The team began the season 13-1, with the only loss coming to the 15-1 Steelers in Pittsburgh.  Philadelphia clinched the NFC East after week twelve. The Packers were the 2nd best team in the NFC, and the Eagles bludgeoned them in December 47-3 before a pair of garbage time touchdowns. Philadelphia had a great defense, but the offense centered around Donovan McNabb, Brian Westbrook, and Terrell Owens was unstoppable. In the 14th game, however, Owens broke his fibula and injured his ankle; expected to miss the rest of the year, Owens returned for the Super Bowl, but it was not enough: Philadelphia fell to the Patriots.

If you are an Eagles fan, that’s some pretty good company: all three teams made it to the championship game.

This year’s team seems worthy of being in that discussion. Philadelphia leads the NFL with a 31.9 points per game average, thanks in part to an otherwordly (and unsustainable) red zone success rate of 73.3%.  The Eagles rank 8th in points per game allowed (17.4), and rank in the top 10 in just about every major defensive category.  The Eagles rank 1st in the NFL in points differential, at 14.5 per game.  That’s also the 3rd best in Eagles history through 11 games, behind the ’49 team (+19.6), ’48 team (17.8), and ahead of the 1980 team (+14.3).

Yesterday, I looked at Pythagenpat records in 2016. Today, let’s look at the Pythagenpat records for each team since 1960. ^[1]Note that since today’s dataset covers a much longer period, I used 0.255 as the best-fit exponent to determine what exponent used for each team. More explanation available here. The table below shows the following information for all 1,613 teams since 1960:

The top team by Pythagenpat winning percentage was the 1962 Green Bay Packers, who scored 415 points and allowed just 148 points. That translated to a 0.929 winning percentage, and an even better 0.934 Pythagenpat Winning Percentage. The Packers therefore “underachieved” by 0.005, which ranks as the 851st best difference since 1960. The team’s main passer (by attempts) and coach (by games) were Starr and Lombardi, of course.

Regular readers are familiar with Pythagenpat Records, and using them to see how much of an outlier teams are in a given season.

You can read the link for background information, but here is the quick summary.

The Texans have scored 161 points and allowed 188 in 9 games this year. We use this formula to determine the appropriate exponent for Texans games:

(Points Scored + Points Allowed)/(Games Played)^0.251

This helps to control for things like pace of games, and scoring frequency. For Houston, that exponent is 2.50. Then, we use that to calculate the team’s Pythagenpat Record using this formula:

(Points Scored ^ 2.50) / (Points Scored ^ 2.50 + Points Allowed ^ 2.50)

At 8-1 — but with just a 0.668 Pythagenpat winning percentage — I wrote about the good fortune of the Arizona Cardinals. Fortune is relative: the Cardinals have lost both Carson Palmer and Drew Stanton to injuries, and just about every key contributor you can think of along the way. But the team’s good fortune when it comes to Pythagenpat winning percentage has continued. (For the uninitiated, you can read more about how to calculate Pythagenpat records here.)

Since that article, Arizona has gone 3-2 despite being outscored by 10 points. That is both a fact and doubles as the most 2014 Arizona Cardinals sentence you could ever write. The 11-3 Cardinals are definitely not the worst 11-3 team ever, but they aren’t too far from the top of the list. If we look at all teams with at least 11 wins in their first 14 games, Arizona checks in as the 8th biggest overachiever. Given that the 2004 Falcons had a worst points differential *and* were fortunate to face an easy schedule, Arizona can’t match Atlanta when it comes to worst 11-3 teams. [continue reading…]

When we think about the most dominant teams of all time, the New England Patriots of the last few years don’t leap immediately to mind. Yet, their performance late in the year has been mind-bogglingly good. From 2010-13, New England went 29-3 in the final eight games of each season, a record that no other team since 1960 can match over any four-year period. Including their three games this year, the Patriots are on a 32-3 run in regular-season games in the second half of the season. From 2010-2013, the Patriots also have the biggest four-year point differential in second-half games in the history of football.

Part of that huge point differential comes from the higher point totals that teams have than they did in the past, and from New England’s offensive-centric philosophy. As a result, when we look at Pythagenpat records, the Patriots are not as dominant. ^[1]I used 0.251 as the value in the Pythagenpat formula to find exponents for each team-year. Here are the hundred best late-season teams over any four-year period, according to Pythagenpat record. The Patriots from 2010-13 rank only 38^th on the list, behind four other recent Patriots’ runs, some of those overlapping with 2010-13. The Patriots have been great and it is an unlikely outcome that they’d have no Super Bowls in the decade so far, but they also have not been quite as strong in terms of their true strength as their second-half records would suggest. As a high-scoring team, we would have expected them to lose more of their regular season games than they have. [continue reading…]
