Boston Celtics second-year forward Jared Sullinger doesn't want to hear that dirty "R" word.

Sure, his Celtics have made some rather large changes to their roster, an offseason overhaul that will soon include shipping veterans Paul Pierce, Kevin Garnett and Jason Terry to Brooklyn. This after coach Doc Rivers fled out west to usher in the makeover process.

But Sullinger gets ruffled at the idea of a rebuild.

"When you have Celtics pride, you really don’t have time to rebuild," Sullinger said on Sunday in Orlando after lending his assistant coaching talents to the Boston summer squad, which lost its opener to the host Magic at the Amway Center. "You've got to play hard, you've got to play smart.

"I think with the veterans we have like Gerald Wallace coming from Brooklyn ... and we have Jeff [Green], everybody counts us out. But we still have [Rajon] Rondo. He won a title in ’08. He knows what it takes. That 'rebuild' word, we really don’t like it."

Sullinger knows that younger core must take on increased responsibilities without the veterans to shoulder the load (and provide a safety net), but the 21-year-old is adamant that there's enough talent in Boston to remain competitive. He bristles at the suggestion of losing in order to aid the transition process.
