Lewis AND OBO? I look at OBO as someone who should be replaced. I'm still not sure why people think he's this great weapon awaiting deployment. It's been four years of this.
I suppose Noteboom has seemed fairly solid (he's not a Pro Bowler or anything) when he's not injured, which again, hasn't been often.
I don't know much about Howard, I couldn't even find college highlights on the guy, just a bunch of interviews, which is very far from what I would expect from a player that is supposed to play a vital role in the defensive front seven.
