Sullivan also played in summer league, tacking on with the Memphis Grizzlies. He played only 14 minutes, stuck behind more established players who are either already on a roster, or who have better chances of making them. Sullivan is a recent graduate of Southeastern Louisiana in the Southland Conference, averaging 15.7ppg, 8.7rpg, 2.1apg, and 3.3bpg in his senior season, the blocks per game ranking eighth in the nation. (Five of the seven ahead of him were draft picks this past summer.) He's a thin but athletic 6'9, who can't shoot or handle physical play, but who can score through his athleticism alone and (obviously) block some shots. You could perhaps liken him to JaJuan Johnson, but without the 20 foot of jumpshot range and the overall poise. And the draft billing.
