Last year if Sullinger had declared for the NBA draft, he might have been one of the top picks. Now he's sliding down draft boards.

Sam Amico reports:

- Jared Sullinger has been red-flagged by NBA doctors, who cited concerns with his back, and most GMs feel that it will, in fact, cause his draft stock to slide. Sullinger's lack of overall athleticism already had created some doubts, and perceived medical issues certainly won't help. That said, the Celtics reportedly wouldn't mind giving him a shot, and might look to trade up (if necessary) to do so. Right now, they own the Nos. 21 and 22 picks in the first round.

- Last time a player was red-flagged like this was 2009, when teams shied away from Pittsburgh big man DeJuan Blair, who doesn't have an ACL in either knee. But Blair went in the second round to the Spurs and has proved to be a steal.

Once again, Danny Ainge loves to look for value. Picking up a guy with injury concerns is a gamble but if it works out the upside is tremendously beneficial. Essentially he's often looking to swing for the fences instead of slapping singles.
