Obviously this could just be coach speak, but one of Sexton's assistant coaches mentioned that he's a much better passer than he gets credit for, largely because Alabama didn't really ask him to be a passer. His job was to score. Plus, it seems like his teammates were hot garbage.
I'll believe it when I see it...
In AAU play, for example, he averaged a record breaking 31.7 points per game (60% true shooting) but only 1.1 assists per game (0.4 ast/TO ratio). That's a crazy degree of ball-hoggery, no matter how bad his teammates sucked. He did a better job mixing in some playmaking in college, but obviously not to the same degree as the typical lottery PG.
He doesn't seem like an incorrigibly selfish personality, but he's clearly a score first ask questions later kind of guy on the basketball court, and that's something that will have to change if he's going to be a real star someday.
