Sources have exclusively confirmed today to DraftExpress.com?s Jonathan Givony that Louisiana Lafayette point guard Orien Greene has been inked to a 3 year, $1.8 million contract by the Boston Celtics. Greene, a 6-5, 210 pound pure PG was the #53 pick in this year?s draft. He was called one of the biggest sleepers in the draft by DraftExpress back in April, but was not invited by the NBA to either Portsmouth or the Chicago Pre-Draft camp after averaging only 11 points a game last season.

The first year of his contract will be fully guaranteed according to the source, while the 2nd year is partially guaranteed and the 3rd year is a team option. The Celtics had to dip into their Mid-Level Exception to lock him up for the three year deal, as Greene will earn more than the NBA minimum.

His agent, Jason Levien was contacted by DraftExpress and had this to say: ?Orien Greene is very excited to sign with the Boston Celtics, after being the only mid-major conference player in the NCAA to be drafted. It?s pretty amazing if you consider that he did not play in even one Summer League game after undergoing surgery shortly after the draft, which should tell you all you need to know about the confidence the Celtics have in his ability as a player. We?re expecting Orien to compete for minutes this year already in Boston.?
