The only way this would be viable is if they literally lowered the rim. But that would just be ridiculous. No such dramatic changing of the core game is changed when the midgets fight. They are just smaller.
Actually I agree. The middleweight division doesn't interest me much at the moment (though I like Martinez a lot), but historically it's been great. I'm also a big fan of Monzon and Hagler, and there have been many great fighters and fights in the division, in most eras.
