QBs today, like
@TerryP mentioned, they come out better prepared. They do the camp circuits, 7 v 7, get respected QB coaches to tutor them, etc. I was a QB coming out of HS and when I walked into the QB room at BAMA as a walk on, I had no clue as to most of what QB coach/ OC Homer Smith was talking about. I knew very little. Granted it was 30 years ago, but the HS game and coaching the QB position have changed. I had no clue about progressions, a route tree, Didn't know where the windows were in 2 deep versus 3 deep, 2 deep man, quarters coverage, etc.
With all of that said, I look forward to the competition this Spring. Mac will be the penciled in starter, but can he hold off Young? Saban fought that urge once and it almost bit him in the ass. Will he be quicker to pull the trigger, should Mac struggle? Young is a talent!! Playing in perhaps the toughest classification and schedules in HS, he faced stiffer competition than what Tua saw on the Island.
