What else can HB do in two series in a game they have already lost? He led them to a TD on the first and was driving on the second. He hit the right receivers in stride. He did not overthrow, used touch when needed, and fired hard when necessary. When it was not there he threw high and outside away so it would not be grounding. He stepped up and shifted laterally as necessary in the pocket. He scrambled once for a 7 yard gain - something Fromm did repeatedly at UGA that everybody on here admired. That moves the sticks. He knows more how to operate at the position than anybody since Dobbs and he had total playing time equivalent of about one quarter of one game. He did that well because he came ready to play from HS. This was already him. It has nothing to do with what this staff did or didn't do with him.
If Salter comes he gets to compete like everybody else, hopefully with a new, real coaching staff that can develop players.
