Suddenly the receivers were running great routs and he was throwing balls to open spots they would occupy at precisely the right time. Cahoon didn't become one of the five all time best receivers in pro football by being lazy or inept. Nelson was simply that bad at quarterback. He did not run patiently through his progressions. He cause a lot of his own sacks, fumble and pics, the latter by tossing the ball to target people rather than target spots. Physical evidence of this was npt difficult to find in the film room. About 7 of 10 Nelson passes were behind or thrown short of the receiver. Are you saying BYU's receivers are too fast? Lark came in and suddenly Apo, Ridley, THE TEs were all open and the ball was being spread around. Lark in two starts showed the patience of a veteran, going through his progressions, demonstrating vastly superior mechanics. It wasn't Cahoon.
