Sullinger has been one of the best rookies in the new year, keying the Celtics to a six-game winning streak by averaging 9.8 points and 9.3 rebounds in 25.3 minutes per game off the bench. Sullinger will likely be one of the rookies playing at the BBVA Rising Stars Challenge, and teammate Paul Pierce says he'd be shocked if he wasn't there. "I think that's like a no-brainer," Pierce said recently. "In the rookie class, I can't even name five quality rookies. [Sullinger] is playing well and playing significantly for the ball club. I definitely think he should be there."
