I feel like in this league you need a combination of elite QB play and great coaching.. as we know we had that for so long.. if anything zappe showed he could be a more than capable back up, and that's an excellent thing for the team going forward.
The point I've tried to make is that compare and contrast Mac's rookie year to this one, clearly the offense is different, Mac shoulders the blame becuase of course he's the qb, however he's doing what the coaches ask of him.. not excusing the turnovers, but that he wasn't in much of these difficult situations last season.. he had heavy use of the TE is hunter Henry still on the team? A 10 touchdown guy last season and he's like non existing..
I think Mac will be fine and continue to grow as he further acclimates to this non TE offensive scheme..
