I agree with
@Faux Sean Callahan on this one. Raiola really came together on his offensive line later in the season.
With that said, I still don't think Raiola will be the offensive line coach going forward. He hasn't been 'replaced' yet, so he is technically still interim offensive line coach until Rhule gets his guy in there. And with your coaching duties, you still go ahead and offer guys you believe would be a good fit. Until he gets relieved of his duties, the continuous work could help him with referrals and good graces with Rhule (for a referral or staying on staff).
