I think this would be a great fight and should definitely happen. Until someone beats him, Casamayor is the top dog in the division. He's the linear champ, and deserves this fight--especially considering that he was the one Popo was supposed to be fighting.

I think I tend to agree with those who would favor Diaz's activity over Casa at this stage of Casa's career. Casamayor's style has reminded me of the later-stage B-Hop style in recent fights--very defensive and cagey, but very offensively inactive. I don't see Diaz landing much clean on Casa, and definitely don't see Casa getting hurt, but I don't see judges giving Casa a ton of rounds where he's throwing less than half as much as Diaz. And I don't see Diaz getting KO'd.
