Randle makes the game far more difficult for himself than needed. Somewhere along the line, it must have gotten into his head that creating the best shot meant putting five moves together before attempting an one-handed push shot with his defender hanging all over him. He just doesn't take simpler, skilled shots like jump hooks or turnaround jumpers. Since he's not explosive from a standstill position and gives up length, he should be working on making skilled shots rather than trying to grind. He's going to finish top 5 in shot attempts blocked if he takes the same approach in the NBA.
That said, he should be a devastating scorer on pick and rolls because he's quite explosive with a running start and has the physicality to get to the line. Unfortunately, Kentucky runs few pick and rolls.
He reminds me of David Lee. Both are 6'9 in shoes, with wingspans and standing reaches one inch of each other. I think Randle has the Lee profile of a double-double guy with limited defensive impact who is a very good finisher as a roll man. Also, someone who is a good passer. Lee improved his jumpshot immensely after entering the league and Randle's going to have to as well.
