Tanner has had the most success throwing to the outside of the field and deep balls. Where he has a low completion percentage is across the middle. Maybe a connection?

Also, Zack and Tanner are both listed at 6'3. Tanner releases the ball near his ear and Wilson is above his head. We are talking about at least a foot of difference in release point.

When Tanner throws, he makes the defensive line an entire 12 inches taller than when Zack is in the game.
