Pocket presence is not running out of a clean pocket to escape invisible boogeymen. Pocket presence is Peyton Manning or Tom Brady taking a slide step to the left to avoid pressure and deliver the ball to an open receiver. Lamar Jackson or Mike Vick had elite athleticism and escapability.
They didn't have pocket awareness or presence.
That's not to say that Kosi can't be successful or has to be Peyton Manning in the pocket, but reports from scrimmages and the spring game suggest he's leaving the pocket too soon and trying to do too much with his legs. He will never start for Mark Richt like that. Richt expects the QB's eyes to be down range at all times. N'kosi is not the best athlete on the team. He's not the best athlete in the QB room. Multiple people have said Cade Weldon is faster than Perry. He's going to get away with things against the 2nd and 3rd sting guys like Owens.
The Lamar Jacksons and Mike Vicks of the world ARE the best athletes on the field almost all the time, and this allows them to do the things they do. Perry has enough athleticism and elusiveness to be an elite QB once he learns that his legs can serve him best only when he's using them to buy time for him and his receivers.
