Kelly's lack of improvement is not terribly surprising.
He's already 24 years old and he spent 4 years in college.
I think any improvement that he realizes at this point will come between his ears.
Without any improvement, he can still have a nice long career. So, not a big deal. Still, I think it's reason to question again why Danny picked him. Selecting a guy like Kelly would have made sense when the team was still trying to contend. Trading up to select a role player without a ton of upside when there were at least a handful of higher risk, higher upside picks on the board just days after you send your team into rebuilding mode, though? I don't really get that.
I think it's worth pointing out that his career per36 numbers are 16.1 PP36, 8.5 RP36, and 2.8 AP36.
This goes along with some very good advanced plus/minus stats.
It definitely remains to be seen if he can ever be a player who can make himself valuable enough to get 30+ minutes a game.
It will certainly be a difficult task this coming year with the seeming glut in the front court.
I agree that a big question mark for him is between the ears. If he can stay confident and focused and keep working on improving during some times that may end up being trying, I think he has the skills to come out of it as a really good pro.
I hope he has the patience, and I hope Danny and Brad have the patience with him.
Sure, in retrospect, it might have been better to go with Giannis or Gobert in the 2013 draft. Personally, I had looked at both those guys prior to the draft and was intrigued, but to be honest, they scared me a bit, as I thought their respective bust potentials were at least equally as high as their respective boom potentials.
I'm guessing Danny felt the same way.
