Von Wafer  is a 6-5 shooting guard who does one thing well: shoot 3-pointers, and according to Hoops World  he will be doing it for the Celtics  this season. Wafer made 39 percent of his 3’s with the Rockets in 2008-09 when he appeared in 63 games and played over 1,200 minutes. Wafer also made 45 percent of his 3’s in his one extended season in the Development league in 2007.
He was drafted by the Lakers in 2005 and has had cameo NBA appearances in each of the last five seasons (Dallas signed him to a 10-day contract this past season but he didn’t see any action). After his breakthrough season with the Rockets, which included scoring 14 points and making a late shot to beat the Celtics — Wafer signed with Olympiakos Piraeus in the Euro League.
Wafer was bought out of his contract only a few months into the deal and he appeared headed back to the NBA, but he reportedly failed physicals with the Grizzlies  and Rockets. He spent the summer training in his hometown of Louisiana and declared himself healthy . It’s still unclear what caused Wafer to fail his physical, but he has had back issues  in the past.
Wafer also clashed with Rockets coach Rick Adelman about playing time and was sent to the locker room during a playoff game, for which he later apologized .
All of that makes this an interesting addition for the Celtics. His shooting ability will certainly be a plus for a bench that could use some. If he can accept his role and do it without complaint then this move has solid potential. If not, then it’s still a reasonable low-cost gamble for a player with an obvious skill.
Wafer gives the Celtics 13 players under contract with second round pick Luke Harangody expected to become the 14th shortly. They also have Tony Gaffney and Oliver Lafayette on non-guaranteed deals. Counted in those 13 contracts players is Rasheed Wallace , whose situation remains in limbo.
