"What happens is on the double move, you take your eyes off of the receiver and take them back to the quarterback, and it's at that point in time when the guy gives you the double move – when you're looking back and he's going on the double move," Pees said. "You have to spot the drive for on the up-field shoulder of the receiver. I used to tell guys that the only way I'm looking back to the quarterback now is through the earhole of the receiver. So if I'm looking through his earhole, I can see him, and I can see the quarterback. If I'm looking back here and he's here, I have no idea what he's doing. If he's here and I'm looking back through him, I know. To me, it's eye discipline."
