Pregame: Williams can unpack his bags

BOSTON -- A few pregame quick hits before the Boston Celtics host the Golden State Warriors on Friday night at TD Garden:

* WILLIAMS SET TO SIGN FOR SEASON: Celtics guard Terrence Williams, on the final hours of his 10-day contract, confirmed he'll be signing with the team for the remainder of the season. The deal, which will likely include a nonguaranteed team option for next season, will allow him to settle in a bit after making a strong impression. How did Williams find out about his new pact? Twitter, of course. "I was like, 'How does Twitter know?' But, you know, Twitter knows everything."

* RANDOLPH KNOWS HIS ROLE: Shavlik Randolph, the third player inked to a 10-day pact out of the Chinese Basketball Association, admitted it has been a whirlwind week since returning from overseas. He says he hasn't talked with coach Doc Rivers about his role yet but will stick with what he knows. "I don’t think he has to tell me. If I go in there, it's to hustle, to try to rebound, try to play defense, take charges -- not get fined for flopping. That’s kinda always been my role on any team I’ve been with. If I’m open, make open jump shots." After averaging 32 points and 15 rebounds in China, he joked about heightened expectations. "I told them I can’t give them 20 [points] and 10 [rebounds] right now," joked Randolph. "Let me get my game legs, I’m still kind of jet-lagged. After I get my game legs, I can give them 20 and 12, but I told them to let Kevin [Garnett] play tonight."

* DOC WILL LEAN ON CORE: Rivers loves to joke that everyone loves the mystery and potential of the backup quarterback. But he hastens anyone from expecting too much from the new faces. Asked if he'd throw D.J. White and Randolph right into the fire tonight, Rivers noted, "I would rather put Kevin and Brandon Bass and Jeff Green out there. You know what I'm saying? Someone else asked me that earlier and I said, 'Guys, we're bringing them in to fill our bench and to help us if we need it. I'm not bringing guys in to take any of those other guys' spots.' Obviously, if one of them comes in and helps us, that's good. But that's their role, to be ready to play. And, if they are not playing, to understand what we're doing."
