Isaiah seems to be aware on both sides of the floor, which is good. The announcers said some good words about him. He was always conscience and close to his man on Defense. He appears to be able to move with the ball well. Brought it up the floor dribbling with both hands a few times. Although, he could have showed some more energy, this game did not show a whole heck of a lot of that. It wasn't a fast pace anyhow...plus Simeon rotated about a dozen players in and out of the game.
He plays on a loaded team. The top 10 players will be in playing DI in the next year or three. Heck, maybe the entire team! Similar situation to Flemming, there are too many good players to get any decent amount of minutes.
He probably learns enough in practice, maybe. No idea on how good the coaches are, as that school could have no coach and still do well with that talent. But I am assuming they can coach.... His real experience will be on the AAU circuit.
