Shaq Says Barkley & Jordan Beef? I AIN'T IN IT!!!

Change Shaq's name to Bennett, cause he says he AIN'T IN IT when it comes to the beef between Michael Jordan and Charles Barkley ... telling TMZ Sports he's staying all the way out of the discourse.

Shaq would actually be a good candidate to Jimmy Carter the situation ... he's close to both men, working alongside Barkley on TNT ... and being frat brothers and friends with MJ.

But when we got him out in DC he made it clear ... he ain't the big Henry Kissinger ... saying he's totally on the sidelines when it comes to the Hall Of Fame beef.
