The guy is explosive as hell, he's a dunking machine. He's very average away from the basket however. That said, I do give him some credit in other areas, as he has seemed to pick up the defensive intensity, he's been far more active I believe.
I actually think he could be a better shot blocker, but I don't think he takes that many opportunities just because he wants to avoid foul trouble and stay on the court.
I think he's also been a better passer this year. So overall I do think his game is overall better this year, but that's just from an eye test perspective. I'm assuming statistically he's improved as well, but clearly has some things he could be better at, like most folks.
I don't doubt he could make a living playing basketball, just not sure it's going to be in the United States when all is said and done.
He's been a good Hawkeye, stays out of trouble off the court, etc., so I wish him well in his endeavors after he's gone, wherever that leads him.
