The biggest problem with the 2014 offense was not having Devante Parker for 7 weeks. The offensive line wasn't great, but having Parker out there for an entire season would have greatly helped that cause. Of course, just as Parker came back, Gardner goes down and we had to put in a true freshman QB who is not even a QB any longer. Even with those issues, we still finished 9-3, which ain't bad. With Parker, I think it's reasonable to believe that we beat either Virginia or Clemson (or perhaps both) to win 10 or 11 games.
The offense was a lot more disappointing last year, that's for sure.
