Rajon Rondo's another reliever in Dionte Christmas

Rajon Rondo, the premier point guard of the Boston Celtics, may have another reliever in the name of Dionte Christmas come October 30. Dionte was an outstanding guard during his stint in the recently concluded summer league in Orlando and Las Vegas. He was invited by the Celtics management for their upcoming training camp to fight for a spot in their roster. Will he be able to make it as the 15th man in the team's line up?
