People can bitch about taylor all they want, but the fact remains without him your one of the worst 5 defenses in the league. He's the only game changing defensive player you have. No taylor equals alot of 30pt games for opposing offenses.
Then again, we are completely moving his position. Sure, the Defensive End is similar to the Outside Linebacker, but it is not the same thing by a long-shot. This same argument can be made for the Roy Williams to OLB talk. We are just assuming he is going to come out and play well in this defense, doing something he has had a bit of experience with by dropping back into coverage. I think the question marks about how Taylor fit into this defense are really pivotal for this year.
