6:36pm: Williams joined his new teammates at shootaround today. The BC product told the Boston Herald that he likes Boston and that he has matured since he was suspended twice in college:
“It’s not about my career – it’s more about my life and getting better in everything. All of your experiences, you take them with you. Hopefully you make the best out of the next step you take, every day.
“I like Boston. In the league you get to know everybody pretty well. I played summer ball with some of the guys, and I played with Keyon (Dooling) in New Jersey. Just try to come in and get to know everybody, get a feel for them, and hopefully they get a feel for you. I’ve talked to a lot of people, and this is a very tight-knit organization led by Doc and KG, and the key is to fall in line and follow those leaders. Then you work hard every day.”
9:38am: The Celtics have officially signed Sean Williams and waived Jermaine O'Neal, the team announced in a press release. ESPN.com's Marc Stein reported yesterday that the pair of roster moves was expected.
Williams, 25, spent most of the season with the Mavericks before he was waived to clear a roster spot for Kelenna Azubuike. The Mavs shuttled Williams back and forth between their NBA squad and their D-League affiliate, the Texas Legends. While the big man appeared in just eight games for Dallas, he played 27 games for the Legends, averaging 15.2 points, 8.9 rebounds, and 2.5 blocks in 28.8 minutes per game. Because he was waived prior to the March buyout deadline, Williams will be eligible for the postseason and will provide frontcourt depth for the Celtics.
O'Neal underwent surgery on his left wrist in March, sidelining him for the season. Since he was in the last year of his contract, there was no reason for the Celtics to keep him on the roster. He'll become a free agent and figures to sign with a new team this summer.
