I didn't write this, but here is a reply to your post -
1. Pats missed the playoffs in 2008.
2. Tell Rohan Davey, Damon Huard, Matt Cassel, et al it's "the system"
3. I'm not going to argue that the Pats defense is as good as it was early in Brady's tenure, because it obviously isn't. But they were one Wes Welker EASY catch from winning the Super Bowl last year with an "inferior" defense. Also, Manning had the same weapons (Harrison, Wayne, Clark) for years. For the most part, Brady's arsenal has been a revolving door.
4. The year the Colts won the SB, Manning had a bad postseason (except for the 2nd half of the AFCCG against the Patriots). The Colts defense stepped up big time in the postseason
5. I'm not putting last night's game entirely on Manning, the defense definitely failed them.
