In a mini-scrimmage the next day, I watched Barnes use one of his go-to moves from the prep summer circuit -- a jab, shot-fake, and right-handed drive -- against Brandon Triche, the starting point guard on a Syracuse team that was ranked No. 1 in the country for a short portion of last season. Barnes blew by Triche, who fell to the floor as he tried to pivot to catch up, and Barnes needed just two long strides to extend and gracefully lay the ball in the hoop.
