"Getting down to 12 is the real hard part because in a lot of respects we ... could have kept 14-15," said USA coach Billy Donovan, who led the 2012 USA U18 Team to a 5-0 record and FIBA Americas U18 gold medal. "There were some tough decisions, difficult decisions, but I think we feel overall that we have selected an athletic and versatile team. Our style of play will be an aggressive, up-tempo, running, pressing style. From an execution standpoint we've got to get better there, a lot of the other teams over there have been together for quite some time and that's probably a strength of their teams, so we felt that we have to rely on some athleticism."
Training camp will continue for the next two days in Colorado Springs, Colo., before relocating to Washington D.C. for practices on Thursday, Friday and Saturday. Team USA will leave for the Czech Republic on Saturday. The World Championship starts Monday.
