It's too complicated coming out of HS and it takes 3 years to get it down for the secondary but there are exceptions. It was ok in the past because players stayed for 4-5 years and GP just kinda moved them along. Of course everything has changed now.......except GP. You don't hear other Power 5 schools having this difficulty. Too much thinking because they are not sure or if they miss GP's signal, so they are hesitant because they don't want to come off the field and he's right in their face screaming at them and he's the one that needs to be screamed at. Our secondary and LB are passive, the worst since 2004.
somehow devonte' fields who was a complete knucklehead off the field could grasp the concept of see ball, run to ball, tackle ball carrier quite well in less than one year's time back in 2012
