Wilder is a biased POS. The fact that he could not bring himself to congratulate Fury on a job well done says a lot about the lack of character of the man. Nothing good can be said of him.
Sorry to get off the subject, but the above needs some context. There were strong rumours going on that Duran was going to 'try something' in that shoot. Strong enough that Leonard took it seriously and told Duran's people that if Roberto tried something, he would "match him." So, who know eh?
He showed good sportsmanship because he won. Soon as he lost, he didn't. He also brought the race element into their fights. Many of his fans ate all of that up. He's pissed off because he lost to a white guy. A brash, **** talking one at that. He feels let his people down.
