I'm not even sure it would be better. Sullivan has been the QB coach and KP8 seems to have regressed. The other option, Glenn Thomas, was supposedly brought in to help Canada develop an NFL level passing game. I don't see any evidence of that. Frisman Jackson as playcaller? It's been reported that one of the reasons Robinson was brought in was because Jackson wasn't "controlling" his room. Meyer the OL coach? No.
I don't know who they could turn to on the staff for the rest of the year, but they better figure it out by tomorrow. Preferably on the plane ride home (sans Canada). And, they should start looking around the league at Assistant Coaches who would make good OCs. smmfh ...
