We're lucky we even got him back for his sophomore year. He's going to the NBA after this season, and if he doesn't we likely just had a very disappointing season
I understand, but self confidence and what motivates people vary greatly.
If someone has a, "winning the lottery" is my only chance in life mentality, you may be right. Others, however, who are more confident in their abilities and potential may think longer term about what they must do to become the best they can be.
JC reportedly told RIP after his sophomore year that one more year of development will lead to a higher draft choice and much greater long term success and the money that comes with that. He was right and RIP hasn't been shy about acknowledging it.
What I see in DC is a kid who loves it at UConn and showed how much he values stability by staying at his high school instead of going prep. He's also been very open about the aspects of his game that need development and the type of improvements he's talked about don't happen in four to five months of one off season.
Besides, he may have dreamed about one day playing in the Maui Classic! So, my bet is he stays at least two more years. We'll know about nine months from now.
