IMHO the only question Coach Mac danced around was "Who is your starting quarterback going to be?" He basically gave two answers during the four interviews I saw. (Paraphrasing) 1) the QB will be the guy who elevates the rest of the offense and gets them to work cohesively as a unit. 2) The QB will be the guy who moves the ball and doesn't turn it over, i.e.throwing to the wrong color jersey. The guy who ends every drive in a kick. Whether that is a FG, Extra point, or punt (after throwing it out of bounds to avoid a loss of yardage or turnover) in order to play the field position game.
Now, I see nothing wrong with those two types of answers at this juncture. It pays absolutely zero dividends for him to answer with a single name before fall practices start. If you think differently then you are delusional.
