I've watched Antoine play 5 or 6 times, mainly in big playoff-type games or against quality teams, and I've never seen him not score. Usually he has scored more than one goal. To me that is greatness - especially since he was often scoring the winning goals, and I never saw his team lose with him on the field. I didn't see BC's tournament last year, where Holland (another great player) apparently was the star, but I would imagine playing with Antoine made Holland's job a little easier. And I bet he got some sweet balls from Antoine.
When I've seen Antoine his dribbling has been a combination of speed and finesse, his passing has been precise and showed real vision, and he's been a sharp shooter. After early freshmen year I haven't seem him put in situation where it was his role to defend, so I have no idea if he's a competent defender, but I've certainly never seen him anything but very strong on the ball. He's too lanky to look really "powerful," but I'm sure he is.
I think it's fair to say he doesn't get to be the preseason best player in the state since he didn't play all of last year, but I'm just saying that I think he was as good as anyone in the state - as a freshman. His potential junior and senior year is scary. Enzo is clearly a great soccer player, and has the body and style of a classic "great," but I think Antoine is more dangerous.
