If you go through all the Pats games from 2000-2006, there are 38 times (including pre-season and post-season) where the Pats played a team for the 2nd time in the same season (or 3rd time with Jets in 2006). I'm not including games across seasons because if you don't change signs during the off-season, there is no helping you. Looking at all games where the offense gained significantly (> 7 points...easier to analyze than yards gained) in the repeat performance, there are only 15 instances of "suspicious" games. I didn't include pre-season since it is hard to draw any conclusions from them. Dropping the games where the scoring differential can be explained by home field, events (Bledsoe injury and Milloy situation) or just team suckage (2000 Pats), you are left with 8 games in 7 years...5 where the Pats offense got significantly better in the later meeting, 3 where the opponents got better: Pats Advantage 2004 NYJ: 13-7 win at home, 23-7 win at NY 2004 PIT: 20-34 loss at PIT, 41-27 win at PIT (playoffs) 2005 BUF: 21-16 win at home, 35-7 win at BUF 2006 BUF: 19-17 win at home, 28-6 win at BUF 2006 NYJ: 24-17 win at NY, 14-17 loss at home, 37-16 win at home (playoffs) Opponent Advantage 2002 NYJ: 44-7 win at NY, 17-30 loss at home 2005 MIA: 23-16 win at MIA, 26-28 loss at home 2006 MIA: 20-10 win at home, 0-21 loss at MIA That's it. I believe you can explain away all of the Pats improvements. The PIT games are easy due to the 2 special teams TDs. The opponent games get a little more difficult to understand the differentials, but that is another story. If anyone can find statistical evidence that the Pats offense improved significantly in repeat performances, I'd love to hear it.
