NFL Overtime Playoff Games since 1970

The overtime result of the NFC Championship Game has stirred up the usual complaints about the 'unfairness' of the overtime rules.

With that in mind, I decided to look through pro-football-reference.com's database to see how many playoff games went to overtime since 1970 (the year the NFL and AFL merged). Here's what I found (winning teams are listed in bold):

Comments:

  • Of the 24 games listed, 17 (70.8%) were won on a field goal.

  • Notice that from 1993-2010, 12 of 16 games (75%) were won by the home team. Which suggests that playing at home is a much more important advantage than winning the coin toss.

  • From 1970 to 1998, 10 of the 269 playoff games (3.7%) went to overtime. From 1999-2009, 14 of the 98 playoff games (14.3%) went to overtime. Clearly, overtime games have become much more common; this issue isn't likely to go away.

  • This suggests it would be interesting to look at the rate of overtime games in the regular season during this era. However, I gathered part of this data "by hand"; there are way too many regular season games to look at unless the process is fully automated. I will eventually get to it, but not before the off season.

  • The result of the first overtime drive for games from the 2001 season to present are detailed here.

Comments:

  • Interesting: SRS picks the Saints. Probably because (as mentioned in the previous power rankings) the Colts have a lot of close wins, and a couple big losses when they pulled their starters. Also, SRS is unweighted, so the Saints early big wins count equally with later closer games.

  • This is the first time since Super Bowl XXVIII that there's been a 1-seed vs. 1-seed matchup.

  • The Colts have been relatively slow on scoring in the first half. The Saints best chance is probably to establish an early lead before the Colts have a chance to get started. Of course, even if they do, Manning knows how to bring the Colts back when he needs to.

  • On the other hand, the Saints are the first playoff team the Colts will face with a legitimate passing threat. The Colts had a middle-of-the-pack pass defense in the regular season, so the Saints may at least have a chance to keep up once the scoring starts.

  • The NFL is actually on a relatively long streak of reasonably competitive Super Bowls. Super Bowl XXXVII (Raiders vs. Buccaneers) was the last one that wasn't within one score into the fourth quarter.

Comments

  • The Colts' 2-score win returns them to the #1 spot (they were #1 in week 14, and #2 for most of the rest of the season).

  • The Saints gain some power on their win over the Vikings, but (since earlier games have lower weight), it also costs them power by giving many bigger wins in their 13-0 start less weight.

  • Perhaps inspired by last years' Cardinals, the Colts seem to have been holding back in the regular season. Of their initial 14 wins, they had 8 by single-digit margins. They had 4 wins by more than 12 points, but all early in the season, and all against relatively weak teams (the Cardinals, Seahawks, Titans, and Rams).

  • Is there a way the Saints don't get crushed by the Colts in the Super Bowl? The Saints were only able to keep pace with the Vikings in the NFC Championship game thanks to 2 interceptions and 3 recovered fumbles. The Colts likely aren't going to be so careless.

NFL Championship Game Pick Results

2009 Navigation Links

Pick results for the Championship Games.

Jets (APR, SRS) @ Colts (Line)
The Jets played their game pretty well. But the Colts never seem to give up or panic when they find themselves in a hole, and a first-half lead of just 11 points is just not enough. Unlike the Bengals and Chargers, the Colts were able to keep pressing and keep scoring, and the Jets limited offense just wasn't able to keep up.

Vikings @ Saints (APR, SRS, Line)
This really should've been the Vikings game. The Saints were mostly ineffective on offense, generating just two drives longer than 37 yards. But turnovers (two interceptions and three lost fumbles) gave the Saints short fields for a couple touchdowns, as well as denying Ryan Longwell a chance at a game-clinching field goal at the end of regulation.

APR  1-15-5

Comments:

  • The Colts will likely stick to the same game plan they used against the Ravens: establish an early lead, take away the running game, and grind the clock.

  • The Jets will likely stick to their same game plan too. They've made it this far with just Sanchez throwing just 38 times in two games. But the Colts defense will certainly be scheming to put Mark Sanchez in a position to throw the ball.

  • The Colts light end-of-season load and bye week for the wildcard round of the playoffs could be a major advantage for them as well. The Jets have been playing for their playoff lives for the last four games.

  • It's something of a shock to me that the NFC Championship game features the Vikings and Saints—the way both teams finished the regular season, I figured one if not both would be one-and-done in the divisional round.

  • One big factor in this game is going to be the Saints' offensive line. If Drew Brees is running for his life like Tony Romo was last week, it's going to be very hard for the Saints to keep up with the Vikings.

Comments

  • The Jets retake the top spot, thanks in part to the Cowboys' complete inability to stop the Vikings' pass rush. The Panthers also benefit indirectly via their week 15 win over the Vikings.

  • The Jets were joined by the Saints this week as the only winning teams not to score first. The Jets are also joined by the Colts as the only winning teams not to score at least 33 points total.

  • The Packers are still the only losing team that scored more than 14 points. Jets @ Chargers joins Packers @ Cardinals as the only games in the playoffs with more points scored after halftime than before.

  • This has been a pretty weak series of playoff games so far. Six of the eight games played have been over by halftime. Five games have ended with the winning team up by at least three scores.

  • The full, 32-team power rankings return, so you can see that the Rams and Lions are still locked in a battle for last place.

NFL Divisional Round Pick Results

2009 Navigation Links

Pick results for the Divisional round.

Cardinals @ Saints (APR, SRS, Line)
Rumors of the demise of the Saints offense are apparently greatly exaggerated. Like the Packers last week, the Saints shredded the Cardinals secondary early and often (though without the Packers' early stumbles). Unlike the Packers, the Saints' defense was able to get pressure on Kurt Warner. And, as you saw, Warner doesn't do well under pressure, especially playing from behind.

Ravens (APR, SRS) @ Colts (Line)
This was a masterful game plan on the part of the Colts, executed to near perfection. On defense, the Colts took away the Ravens' main offensive weapons: Ray Rice was held to just 67 yards rushing, and Willis McGahee was a non-factor. On offense, the Colts established a two-touchdown lead by the end of the first half, and spent the second half grinding out the clock, and keeping the Ravens away from the endzone.

Cowboys (APR, SRS) @ Vikings (Line)
How did the Cowboys ever get to 11 wins with such an awful offensive line? Romo was sacked 6 times, constantly harrassed—it's no wonder the Cowboys couldn't sustain a drive all game long, and after the Vikings got their second touchdown, the game was never in doubt.

Jets (APR, SRS) @ Chargers (Line)
As advertised: Sanchez threw for just 100 yards, Green and Jones ran for 169 yards, and the defense held the Chargers to just 14 points. How is this the same team that couldn't beat the Falcons in the Meadowlands in week 15?
