It's funny, but shooting has derailed more basketball careers than anything else. That was Terrelle Pryor's weakness. It is why a kid like Micah Mason who was poo pood here was successful in college. It is what got TJ McConnell to college even when he was way undersized and didn't yet grow.
So many of these great athletes in HS just can get whatever they want on a HS basketball court, they never really focus too much on a jumpshot.
Hell, that was primarily our achilles heel from the guard positions on even our best teams.
