I took note during the year of how Pitino was visibly frustrated with Jamir's defense on multiple occasions. It really stood out to me because his reactions of frustrations towards Jamir's mistakes and his quick hooks of Jamir were in contrast to how he seemed to react to other's defensive mistakes. I am not surprised Jamir has moved on and I wouldn't be surprised if he was encouraged to.
That said, I liked Jamir's potential as a shooter. It's not just that he was a shooter, but that he was a shooter capable of giving you 3 point shooting in many different ways: he had deep range, he was comfortable shooting off dribble handoffs, he'd shoot off the dribble himself...he was much more than just catch and shoot guy. Obviously, he didn't shoot it well enough as a Freshman to justify his limitations. I believe I posted on the board a few times after watching him play in high school that he really didn't have a position to guard. He doesn't handle it well enough or create well enough to be a lead ball handler himself and he's not big enough to guard opponents two guards. He was likely always going to be a bench player, but I think he could have been a nice piece to have provided you didn't need him to start. That's assuming he gets that 3 pt % above 40.
