Celtics draft pick J.R. Giddens agreed to a two-year guaranteed deal with an option for another two years with the club on Thursday. The 30th overall pick in the first round of this year's NBA Draft will begin working out in Waltham at the team's training facility next week. The former New Mexico star averaged 16.3 points and 8.8 rebounds as a senior last season. The Celtics also still have a second round pick that's unsigned in guard Bill Walker.
"He's pretty darn excited to be a part of their team," said Aaron Mintz, Gidden's agent.
