I didn't know Khabib had that attitude, but after listening to DW last night discuss his talk with Khabib-- I'm thinking now that Khabib is the one turning the GSP fight down, not GSP asking for too much. Khabib has often mocked his would-be opponents age before, and GSP being 40 likely put a massive dent in his interest. that FOUR digit is likely something he can't take serious at 155.
Khabib made reference to the fact higher weight classes tend to have a higher average competitive age during the Ferguson press conference, and that being 35 and up is maybe acceptable at heavyweight. I have to say in light of all this, I really think the GSP thing is dead in the water and Khabib himself put the nail in it. I had it backwards and was buying the GSP diva stuff, but not anymore.
