I've looked at sending McCants to CHA many times because of the fit. McCants, Felton and May all had their numbers retired by UNC.
The problem though is that if McCants doesn't like being a sixth man here, he'd hate being a seventh man there. The Bob's plunked a lot of money and a lottery pick into adding Jason Richardson, Matt Carroll's deal runs through 2013, and they still hope that lottery pick Adam Morrison will become something.
Maybe this could work as a three-team deal, but Charlotte's got no room for McCants.
