This one's just for fun -- I ran across this link with 10 of the best commercials ever featuring NBA stars. Check it out.
Michael Jordan is in four of these, including one with Mars Blackmon, one with Larry Bird (the famous H-O-R-S-E game, check out the sweater MJ wears in it) and my favorite, which is the "Jordan vs. Jordan" ad. The reason I like that one so much is that it's the most authentic -- Jordan's trash-talking in it is far more genuine than the cuddly persona he presents in some of his other ads.
The Larry Johnson "Grandmama" ad seems a bit dated now, but still fun.
