Petermans release is too slow, and that should be obvious in practice. I don't see how he is an option if Worley goes down or next season. Dobbs gives you mobility at the very least.
I think his mechanics are fine.
He just hasn't had enough game reps for the game to slow down for him.
He may not be the answer but just like we have all seen Worley grow up before our
Eyes on the field, Peterman will get there. He is however taking his lumps.
