I can help with that. I just rewatched the Nebraska game on B10. There were four targets to Fant in that game...one would have been a long touchdown...where Stanley wasn't even close. Fant's head just dipped a few times...like what the hell. If you multiply that be 3 to 4 targets a game where the ball isn't catchable...well. That is a contributing factor.
The thing I don't understand is that Stanley will then come back and throw three or four balls right on the money. He simply has to improve mechanics or something to be more consistent. I think he's where he needs to be in reading defenses...he just needs to get to 65-68% in completions. Thats a huge difference maker this year.
