-Our inside linebackers are by far the slowest in the league. Adalius Thomas was brought in because he had both the size and speed we need at ILB. When he was switched to the outside, it exposed Bruschi and Seau, who are great leaders and technicians, but get caught up in blocks because they are too slow. Vrabel, Bruschi and Seau are great at going straight ahead but have a lot of trouble changing direction. Crossing patterns kill us.
-Our 3-4 defense is based on stopping the run first, which was great a few years ago, but this is now a passing league. We changed our offense to reflect this, but the defense did not. We get little initial pressure on pass plays with three or four guys going after the QB. Look at the rest of the teams left in the playoffs, they have at least two guys whose specialty is rushing the passer trying to shoot the gap on every down. With our 3-4 principles and Seymour less than 100%, QB's have too much time on 1st and 2nd downs to survey the field. Our best pass rushers are often dropping back in coverage (Vrabel should never be in coverage).
As other posters have mentioned, the Pats D have executed gameplans very well. Some examples:
Philly: The Pats wanted to control Westbrook and force Feeley to win the game. Problem was Feeley played out of his skull and the DBs were always just a half step slow.
Balt: The Pats were completely flat coming out of halftime and got run over for 2 TD drives. Can't explain why, but the other 3 quarters were solid.
NYG: Eli played better than expected but game was generally going according to plan at halftime (return TD skewed the score). Again, a dud drive starting the 3rd quarter and an uninspired effort by the D made it look bad.
These are games people use as examples that the Pats D is struggling. In reality, they all followed the same basic script:
1) Play conservative in the 1st half and see if the opposing offense will beat itself trying to compete with the Pats scoring.
2) Drink some warm milk at halftime and sleepwalk in the 3rd quarter.
3) Wake up and shut down the opposing offense in the 4th quarter.
The only thing that disturbs me is the lackluster effort after the halftime break...particularly since implementing halftime adjustments is typically a strength for this team.
If the Pats were fundamentally flawed on defense, wouldn't Dallas (3 pts on a short drive), Indy (7 pts on a short drive), Philly (nuthin), Pittsburgh (zip), Giants (7 pts, Pats trading points for time) and Jax (3 pts) be able to take advantage in the 4th quarter? The Pats keep their powder dry until the second half and are able to go all out on defense to close out the game.
