You know you’re desperate for a big when … as the Boston Herald reports: “As a testament to the Celtics’ willingness to kick the tires of every big man who might help the cause, Danny Ainge and Doc Rivers have set up a meeting with Kwame Brown tomorrow in Orlando. ‘We’re checking out a lot of possibilities – it’s still very early in the process,’ Danny Ainge said today of what is certain to be a broad casting call for big men, including Shaquille O’Neal. Ainge said he has not set up a meeting, to this point, with O’Neal. The 6-11 Brown spent the last two seasons with the Pistons, and in strictly a backup (13.8 minutes per game) role averaged more rebounds (3.7) than points (3.3) last season. But his value as a shot blocker (0.6 career average) may be what the Celtics are looking at now. Brown, of, course, is better known as one of the greatest draft disappointments of all time. Michael Jordan selected him for Washington with the first pick of the 2001 draft, and as the first high school player to ever go with the No. 1 pick, Brown never came close to living up to his draft pedigree. But after four NBA teams (Wizards, Lakers, Grizzlies, Pistons), Brown is simply attempting to catch on as an experienced backup. ‘He lives pretty close to (the Orlando Summer League), so he’s going to drive down to meet with Danny and Doc,’ said agent Mark Bartelstein. ‘They want to get to know him a little bit.”’
