Absolutely, they played the Colts using only 2 D-linemen at times. How do you stop big backs like Bettis and (to a lesser degree) Staley with 2 D-linemen?
Not very well which is why they won't do it in this game.
A little perspective for you:
Corey Dillon: 1635 yards, 4.7 ypc
Edgerrin James: 1548, 4.6 (against Patriots: 39, 3.1)
Jerome Bettis: 942, 3.8
Duce Staley: 830, 4.3
Kevin Faulk: 255, 4.7
As big a choke artist as Peyton Manning is, he's a far superior QB to Ben Roethlisberger. Now, I can't guarantee that we'll limit Bettis to 8 yards like we did in 2002, but he sure as hell ain't gettin 100.
Different defensive scheme. Bet you might see it if the Pats are up and Big Ben has to pass a lot.
