JO could easily have a very long career in the NBA. He is still a work in progress, but shows touch shooting a midrange J and at the FT stripe. His slender frame is a drawback, his hands are poor and he's not exactly a deft passer...but the shotblocking ability is a potential draw. Needs to show he can rebound consistently next year IMO. Also, maybe not drafted, but could still have the longest career.
Rodney can't create his own shot. But hey, neither could Cariter Martin and he got his cup of tea with a few teams. Rodney is a solid defender and sneaky rebounder as well. Not probable, but possible depending on improvement next year.
