If all fights were to be fought under the rules of the JBE- that is, the Joe BoxingCouncil- all weigh ins would take place 6 hours before the fight. There would be one champion in each weight class, and i'm pretty sure I would eliminate a bunch of the weight classes. i don't think i'd go back to the original 8, but there would be less than there are today.
There would be more cheerleaders involved, maybe multiple ring-card girls. I used to like getting to the Forum early for the bikini contest featuring potential Miss Ringsider contestants. (Incidentally, some of those girls made more than world ranked jr flyweights fighting 10 round fights.)
There would be qualifications before you were allowed to fight for a title. Maybe, beat three top 10 guys, or draw a $500,000 live gate. (We'd have to adjust that based on local ticket prices.) The whole point being, the guy can either fight, or draw fans.
I have no problem with "bad" decisions. They get people talking about boxing, and even great fights don't do that. most sportswriters and, these days, radio hosts, are fucking morons, so i would ban them from fights, with an explanation that they are too stupid to understand the activity, anyway.
I would ban any use of the word "sport" in relation to boxing, and make all potential commentators sit down and watch 100 hours of fights with me, so we don't have the public perception of boxing being tainted by brain dead know fuck all nothing "experts" like Lampley, Bernstein, Merchant, kellerman, etc...etc...ever again.
