Here's a question,
Is there a minimum weight for Heavyweights?
I know the div is for 200+, but Roy Jones fought Ruiz at 190something if I'm not mistaken.
So is there a definitive minimum weight a Heavy must be to fight for a title?
Assuming a sanctioning body allowed it, can someone that's, say, 160 pounds fight for the Heavyweight title if he wanted to?

These are the pressing questions at hand.
