Someone was saying he'd fit better in the 3-4 but he is definitely a badass.
Depends on the scheme.
This is not like your daddy's 3-4 vs. 4-3 debate.
We are conditioned to think like that because, well, we are running our daddy's 4-3 with old man Marinelli.
Hybrid schemes can fit in playmakers.
Look at what Seattle did with Bruce Irvin. He wasn't a LBer. He was not really an every down DE. But he was an effective player if used in the scheme correctly.
Today's game is not about finding the perfect fit for your limited system. It is up to the coach to make the system fit the players.
That is one thing Wade Phillips has always done. He finds a way.
Guys like Marinelli? They sit around waiting for the perfect "rush man" and downgrade players because of lack of his required amount of "twitch".
