I don't think that our Defensive coaches were ready for the new rule changes, which really has resulted in a change of the way the game is played. QBs have been breaking records all over the place this year, and that alone should tell you how the NFL has changed.
When you look at it, we've never been very good at rushing the QB. Even in our rookie season, we were just OK. But what we did have was good run coverage and good pass coverage. Now, pass coverage has gone out the window in today's NFL, and if you want to play good D, you really need to get pressure on the QB. Now, we need linebackers with lots of speed and with the ability to attack from lots of different angles. Peek is probably our quickest linebacker and has got to be in there. If he's bad at run coverage, than put him in the game and let him learn!
I expect Capers, a defensive guy, to get this D together and build some consistency. I've never seen us get burned on 3rd and long like we did this season.
