Over the years I've met many many fighters and become friends with many of them Most of them were nice in fact all but one were great guys. The only "bad guy" was Riddick Bowe a few years ago.
He was at a black tie fight card in Dallas as a guest of honor. It was the anniversary of Pearl Harbor and the marine color guard were there . All he did was hang with them ignoring fans wanting autographs. It wasnt long after that he had his short career as a marine ROFL he didnt like being shouted at so he bought himself out
