since this is the "Internets", I have to challenge your original claim that "But I promise you. I could perform at that level physically." What exactly does that mean? That you could keep up with the drills. I commend you for being (apparently) quite the physical specimen and in great shape, but I must say it sounds like a colossal oversimplification on your part. Desire & attitude have served me very well in my career but I could IN NO WAY equate these qualities to my performance on the playing field. Aptitude is an intellectual capacity and personality is a subjective, qualitative trait; athleticism is the physical capability to perform said tasks per sport. I think you are reaching here, and have quite the stones to boot.
I am not attacking you personally, just challenging your claims & logic. Sounds like you'd blow us all out of the gym, and I tip my hat to someone of your ilk ....
