Would it sell? Hell yeah.
Is it relevant? Nah, but you know you'd watch.
Real question is if Diaz was in way serious and could get under 185 ever again, cause he looked like the 209 pillsbury dough boy. For name vs name this is like a casuals wet dream. Hell man, people at the bar last night thought Diaz was still a bad ass based on name only, had no clue he hadn't won a fight since 2011, and hadn't fought in 6 years. Oblivious... but the names sell, and this fight would sell hard even with this most recent fight.
