Sirianni is a mid level head coach who's carried by his GM and coordinators. When he sucked an play calling he turned it over to Shane who got the offense clicking all the way to the Super Bowl. Shane leaves and the offense falls off. Nick refuses to take over play calling. Kellen comes in and they win the chip. Kellen leaves and the offense is back to looking as bad as 2 seasons ago. Nick refuses to demote or fire his guy he promoted to OC. He refuses to take over play calling.
The front office should step in and fire Patullo. Nick won't do it because he knows if he has to call plays he'll get exposed. If they flame out in the playoffs he should be on the hot seat if not fired.
