Depends, I choose to spread the blame around and not lay it all at the feet of the starting QB.
Although we have a talented receiver room, we have exactly one of those guys to meet or exceed expectations. The two most explosive playmakers on the offense have either been hurt or a non factor(turnover machine) for the toughest stretch of the schedule. But, but but the QB. Many might argue that Baxter would have been another potentially explosive playmaker but we haven't seen him either. If people would take a step back and actually analyze the root causes and contributing factors they will find and admit that this isn't just a QB problem.
Funny how people want Arch to come in in RZ because he is a run threat. That alone should give them the clue they are looking for. The statistics for the run game in losses and RZ for the entire year tell you where the problem lies. It's up to the HC/OC to figure it out. Based on what I saw against Clemson, I think he did but some of you probably didn't even realize what changes were made.
