Even the game was different. The city game in which Dockery thrived -- taking on Georgia Tech's Will Bynum and Oklahoma State's Tony Allen from Crane Tech and the occasional suburban interlopers such as Dee and Shannon Brown from Proviso East -- was one of nonstop fast breaks.

"You wouldn't need a shot clock," Krzyzewski said. "There are a lot of possessions, and each possession isn't what it nearly should be worth. So Sean's had to change his game to play at this level."
