Celtics sign first-round pick Giddens

BOSTON -- The Boston Celtics signed first-round draft pick J.R. Giddens on Tuesday.

The 6-foot-5 point guard, the 30th pick in the draft, averaged 16.3 points and 8.8 rebounds for New Mexico during his senior season.

Giddens, 23, brings a reputation as a strong defender to the defending NBA champion Celtics.

Giddens said he has matured in the last few years. He pleaded no contest to a misdemeanor battery charge after being stabbed at a bar fight in May 2005 while playing for Kansas. He transferred to New Mexico, where he was suspended twice in his first season.
