While you may have beaten the odds, the chances of turning pro remain slim - roughly 1 out of every 6,000. I would think that the parents would have to reiterate that football isn't everything and only a handful of people actually get a chance to make it big. I am thankful that I had the opportunity to make it. When I was younger if my grades weren't good enough I wasn't going to get to do anything else. I think depending on your position there are certain drills that you can learn from any football coach.
Football is a matter of short bursts and cutting.
Any type of cone drills would be great. Short bursts going forward, backward and lateral. I think those specific drills pertain to any type of position in football. I think it's both physical and mental. If you approach it the same way you approach a classroom you are going to study your plays until you have them down where you don't even think about them.
