The stage is set for Kyrie Irving to make his long-awaited season debut Sunday afternoon against the Philadelphia 76ers. Although nothing is official, Irving, 23, has done all that's asked of him. The team continues to say he needs to pass a few more tests, but sources say the fifth-year point guard has been ready, and his teammates have played a major role to get him there. The Cleveland Cavaliers, winners of their last four games and sitting at the top of the Eastern Conference, executed their plan to perfection during Irving's recovery from knee surgery: They have played well and kept unnecessary pressure to return from creeping into Irving's head.
