He should have been gone after last season. His scheme is difficult, but very effective. All defenses rely on talent, but he relies on smart LBs and secondary. Disguised blitzes aren't easy to pull off... and they won the post season because of them.
TBH that's why I'm a little concerned about losing Gay. It seems they have a ton of confidence in the Tranquilizer... he did pretty well when Gay was injured.
But yeah, we're lucky teams seem to be hesitant on hiring him as HC... and I'm selfishly ok with that.
