Celtics sign G Jamar Smith to a partially-guaranteed minimum contract.
Smith shot 39.3 percent from downtown while playing in the Czech Republic last year, and was similarly proficient during Summer League in Orlando. He's likely to end up back in the D-League unless something happens to Rajon Rondo, Jason Terry and/or Keyon Dooling.

Celtics sign C Jason Collins.
Collins was another veteran's minimum addition to Boston's bench, where he'll spend more time mentoring rookies Fab Melo and Jared Sullinger than he will actually playing. Even Chris Wilcox is ahead of Collins on the depth chart, but he'll be useful defensively against monsters like Dwight Howard.

Celtics sign G Dionte Christmas.
Christmas was offered a partially-guaranteed deal on the strength of his play at Summer League, where he averaged 14.2 points and made 45 percent of his 3-pointers. Even if the 6'5" SG manages to make Boston's regular season roster, he won't be worth owning in fantasyland.

Celtics re-sign G Keyon Dooling.
Dooling missed 22 games due to injury during the shortened 2011-12 season, averaging 14 minutes per game, and we don't expect his playing time to increase with both Courtney Lee and Jason Terry filling out the Celtics' backcourt. The deal is for one year at the veteran's minimum.
