Bruce Irvin is doing what he needs to be exactly doing.
Since Bruce has been at LBer, opposing TE's had a considerable drop in production against us and that hasn't really changed since Wright has been out.
Not only that he has been very stellar making tackles in the right flat as well as keeping QBs contained for the most part, he hasn't been getting sacks because he hasn't been getting pass rush snaps, and when he has I've seen him apply pressure with someone else ending up with the sack.
Right now Irvin is a coverage LBer, considering his athleticism + length, he's probably the Seahawks best coverage LBer. With Avril, Bennett, Clemons, and McDonald all sharing the majority of the Pass Rush snaps, Irvin is better used in coverage.
And again imo opinion while I thought he was going to have 12 sacks this year, he's doing everything he needs to be doing to position himself as the LEO of the future.
Taking on blockers, making solid tackles, setting the edge, dropping back into coverage plus his pass rushing ability he got to work on has a rookie. All that will add up into a better player as he continues to make progress.
Nobody thought Bruce would be this far ahead of schedules in terms of making the switch to playing LBer. I remember many thought he would fall flat on his face but he hasn't. And he should only continue to get better and better with more experience.
Whether Bruce Irvin is the potential LEO of the future, after Avril or he continues as an athletically unique SAM linebacker, Seahawks got a solid player who is growing into a better one each day, each game.
And by unique, I mean not many LBs can cover WRs, Bruce Irvin can at 6'3, 250.
