The more I think about it, the more I feel MB has been HC ( even tho Oshea does the PR. Clearly Osh has expressed disappointment with the O yet does nothing as the HC to change any calls admiting he's got nothing to do with the offense. I have a feeling Oshea n MB will be let go together and hall will be promoted this offseason based on results. In essence cutting our STC n OC but making our DC the new figure head and let him bring in who he wants

The fact that O'Shea has said anything negative about the offense at all should be a giant neon sign flashing that says Bellefool is on his way to the unemployment line when the season is over. Seriously, O'Shea never says anything negative, that he's called out the offense for not being good enough should speak volumes on what he thinks about the offensive coordinator. He gave them a chance for continuity, it didn't work I truly do believe a change will be made there this offseason and I think everyone knows it. 

Agreed. The only question is the degree and timing of the change(s).
