from the info on here it looks like he graduated from Ossining in 2016 and went to Mt. Zion Prep. Only watched the first basketball video but he looks like he can shoot from distance and go to the basket.

3 things impressed me in particular.
1) There was a reach back steal and immediate transition end to end where he finished with a dunk. It showed a willingness to get into a passing lane, acceleration in the open court, decent enough handles, and some ups.
2) He made an entry pass in the post after a ball reversal and pin down by the post (at least it looked like him making that entry pass). Either it shows someones ability to anticipate when someone is about to get open, or if he was actually the post player, and ability to know when to get your rump into someone to create a passing angle. Either way....a bit of hoops IQ.
3) There is a football video on there...not that I think Lovie is going to come ask him to hop on the football field if basketball doesn't work out, but just the factt hat he played another sport in high school...I'm a proponent of (my personal opinion of course)
