If there is no science behind it go find me the 5"10 qbs in the NFL and get back to me. Why do you think everyone pulling for Tate is saying we should be in the shotgun.
Being 5"10 at best and throwing over guys that average 6"3 to 6"4 takes away the area right behind the d-line because he cant see. He would have to find throwing lanes on every pass in that part of the field unless he takes a deep drop.
