And whoever controls the line of scrimmage wins the game. The reason that offense is impossible to shutdown is because of Brady's ability to sit in the gun and take his pick of 4 or 5 receivers anytime he chooses. The offensive line is the key to the success of the Patriots, and even if you do get some pressure, as the Cowboys were able to with Demarcus Ware (and the Skins probably will with Andre Carter from the same side) it's still a case of that offense having way too many possessions and eventually wearing you down.
The Patriots' O presents a nightmare regardless of the strength of the defense because:
1. The O-line rarely misses their assignments and protect the blitz particularly well
2. Brady to Moss
3. The sheer number of capable receivers at Brady's disposal and the combination of routes and threats presented at each level of the defense makes it almost impossible to get sack the guy, be it via good coverage or blitz scheme.
4. Brady to Welker
5. Brady's ability to read, make his decision quickly, and make ALL the throws means that the Pats can call anything they want, regardless of the situation.
6. Brady to Moss
7. Most of their backs, particularly Heath Evans and Kevin Faulk, are above-average receivers, further extending Brady's options.
8. Oh yeh, Brady has Moss, Welker, not to mention Watson (not sure about his status), Stalworth, and Gaffney... ALL above-average receivers, in my opinion.
The Redskins running and short-passing game absolutely has to be in-tune this weekend. The defense is gonna have to make some plays and cause some turnovers or cause some Patriots not to be able to finish the game.

The Patriots prefer to stay on the outside, dance and look pretty, and land bombs upside their opponent's head. The Skins have to stay right in their chest, grab, hold, low blow here or there, head butt, etc..
It's gotta be an ugly, difficult-to-referee fight for the Skins.
