It's just something I can't imagine any of the true champions of the past doing.
Chuck, Wanderlei, Nog, Randy, BJ... I just can't see any of them saying 'no' to a replacement.
Bones is a new type of fighter in more ways than one. One of the big differences is because he came up after the sport was already established, he doesn't feel the same level of appreciation for and obligation to the fans as the last generation of fighters did.
Also, his comments about 'carrying the cross' for the UFC made my freaking blood boil and I'm not even a Christian. Don't compare yourself to Jesus, it's not a good look.
