Hey, hey, hey....
Is he related to Mel Turpin?
I watched the workout and it is no wonder he is hefty. That workout was pitiful and looked easy as cake. Dude needs to be doing a mix of fast cardio and weights to lose pounds. The medicine ball shot with his shot is too increase range. He has a nice touch inside of 17 feet. I think he is weak on the range of his three and it messes with his release. Strengthening it where it is a more natural shot may help him.
