Sullinger chipped in seven points (2-6 FG, 3-4 FT), an assist, six rebounds and two steals over 11 minutes in Thursday's 111-96 victory over Real Madrid.

Sullinger, already battling for playing time after the Celtics' off-season acquisition of David Lee, saw a drop in playing time from the exhibition opener, when he logged 15 minutes on the court. Nevertheless, the 23-year-old power forward was active and productive on defense Thursday, collecting five of his six boards on the defensive glass and adding two swipes. Although he clearly finds himself behind David Lee at the moment, the 32-year-old starter's likely minutes cap could very well help buy Sullinger extra time on the court over the course of the season. Due to the existing questions about his usage however, Sullinger's draft worthiness remains uncertain at present.

Sullinger played 15 minutes in the Celtics' preseason opener Tuesday against Italian club Olimpia Milano, scoring 14 points (7-10 FG) and adding four boards.

Considering the level of the competition, not much should be gleaned from Sullinger's performance, despite his highly-efficient numbers. Perhaps more notable was the fact that Sullinger wasn't among the Celtics' first four big men to enter the game, according to Scott Souza of the MetroWest Daily News reports. At this juncture, it appears coach Brad Stevens is leaning toward using David Lee and Tyler Zeller as his starters in the frontcourt, with Amir Johnson and Kelly Olynyk ranking as the top bigs off the bench. If that trend holds, there may not be many minutes available for Sullinger when the regular season opens.

Sullinger has trimmed down noticeably, according to coach Bradley Stevens, Jay King of MassLive reports. "He wants to be in the best shape of his life, he wants to be in great condition, and he's working towards that, and I think he's excited for a new season to show that's been his focus and to show off the work that he's put in to get there."

Sullinger struggled early in his career due to back problems, but once those subsided, his weight and conditioning remained issues. He sat almost the entire second half last season due to a stress fracture in his left foot before returning in April. The addition of Amir Johnson and David Lee crowds the frontcourt rotation, and Sullinger needs to improve his conditioning heading into the final year of his rookie contract.

Sullinger finished the 2014/15 regular season having appeared in 58 games (49 as a starter) averaging 13.3 points, 7.6 rebounds, 0.7 blocks and 0.9 made threes per game.

A late February foot injury was supposed to knock out Sullinger for the rest of the season, but he was able to make a surprise return in April and average 20 minutes per game during the Celtics four playoff games. Still, GM Danny Ainge made it very clear that Sullinger must improve his conditioning if he wants to maintain a prominent role with the Celtics. Sullinger has averaged 59 games played per season for his first three NBA Seasons. His 6-9 frame is generously listed at 260 pounds. Sullinger has two more years remaining on his rookie contract.
