Hoop Summit: Five things to watch

The Nike Hoop Summit (Saturday, 7 p.m. ET on ESPN2 and WatchESPN.com) is a unique postseason high school basketball showcase. Unlike other all-star games, the Hoop Summit features a USA vs. the World format that often makes the game more competitive and gives the players a little something extra to play for.

This year’s USA squad is comprised of 10 of the best players in the Class of 2013: Aaron Gordon (Arizona), Aaron Harrison (Kentucky), Andrew Harrison (Kentucky), Kasey Hill (Florida), Rondae Hollis-Jefferson (Arizona), Demetrius Jackson (Notre Dame), Jabari Parker (Duke), Bobby Portis (Arkansas), Julius Randle (Kentucky) and Noah Vonleh (Indiana).

The World team, meanwhile, features top 19-and-under players from across the globe, including three prospects who play high school basketball in the United States: Canada’s Andrew Wiggins (uncommitted), Cameroon’s Joel Embiid (Kansas) and the Dominican Republic’s Karl Towns Jr. (Kentucky).
