My impressions from watching him in 3 games: Team-first player, non-stop motor, very athletic for his size, better defender than I thought (quick feet), aggressive rebounder, good shot-blocking instincts, good handle for his size; can go left or right, no apparent post-up game.
He went to the line often and seems to be about a 75% free throw shooter. From what I observed, he made about a third of his 3-point shots but clearly has skill from 3-point range. He will get stronger and, if he stays 3 or 4 years, he will be a major contributor. We are very fortunate to get this kid.
