I wouldn't read too much into it. Realistically we had zero chance to win this game today, why through Arnaud or Bates to the wolves? You have to carefully develop young QB's more times than not. Ruining their confidence is not carefully developing them. I still think that Arnaud should of had more chances to throw the ball at the end of the game.
IMO Flynn's QB skills were severely damaged by his freshman campaign, and so was Meyer's last year. I am not saying Meyer was ever a great QB. (In fact, I still believe Flynn was a scapegoat, and never got a fair shake.
