From Irving’s twitter feed:
Irving was drafted #1 overall by the Cavaliers after having a stellar season at Duke, albeit one cut short by injury. Nike needs no introduction -- it changed the way team sport athletes are marketed along with David Falk and Michael Jordan, and is synonymous with shoes and athletic wear everywhere. Details of Irving’s deal have not been revealed, but it’s fairly safe to assume that Irving’s deal is smaller than the $90 million deal Cleveland’s last #1 overall pick signed with Nike before he’d played his first game.
