Chaels run is Silva, Stann, Bisping, Silva, Jon Jones - i would say that is harder...not that it matters. Fact is Lesner got a shot from beating Heath Herring and losing to Mir. Not that great, did not deserve the shot.
Him and Chael got shots on there abilty to sell fights - as did the others i mentioned.
Yeah but I think it's unfair to mention it when Brock actually got the belt. He proved that it was right to give him that oppertunity, and he had I think 2 defences against top level opposition.
I never actually thought about Chael's streak since it'll probably be a losing one. Still rank Brock's higher. Cutting out Herring for being B list, Couture (HOF world champion), Mir, Carwin, Velasquez, Overeem.
