The champ doesnt have to prove a damn thing...its up to the challanger to prove he is ready to be a champion
Well he kinds does have to prove stuff, so if some heavey weight cought brock with a lucky shot then avoids fights, that man aint a champ in my eyes, or like Tito when he dodged Chuck. Just coz your the champ dont meen you can avoid stuff just to keep your wins up.
