Former Michigan basketball star DeShawn Sims signs free agent deal with Celtics

An opportunity for an opportunist.

That's how former Michigan basketball star DeShawn Sims used a portion of his allotted 140 characters on Twitter to announce he had agreed to a free agent deal with the Boston Celtics on Friday.

Neither Sims nor small forward Manny Harris were selected in Thursday's NBA Draft. Harris was ESPN analyst Chad Ford's top remaining prospect following 60 picks had been made just before midnight Thursday.

Sims did not return phone or text messages seeking comment Friday night.

Sims averaged 16.8 points and 7.6 rebounds per game during his senior season at Michigan. The 6-8, 235-pound forward hadn't drawn as much draft attention as Harris prior to Thursday's draft despite making a strong showing at the Portsmouth Invitational earlier this summer.

The Celtics selected former Texas guard Avery Bradley and Notre Dame forward Luke Harangody with their two draft picks Thursday.
