JG was a liability in the passing game. He didn't move the O well. Later in the season he separated himself by managing the run game better than either of the other two.JG isn’t great but he was a lot better than Shrout or Maurer. If he’s still struggling early on I would just go straight to Bailey. Nothing to lose in a year like this anyway.
However... he probably would not have started again if Maurer could have stayed healthy. Whether at any point the coaches considered him "a lot better"... they did not consider him good enough. And they were willing to take a shot on a true Fr that wasn't ready to play.
