The sport would benefit from a reduction in sanctioning bodies. A lineal champion in each weight class would do boxing the world of good.
At the moment, we have three world heavyweight champions holding four belts between them - ridiculous! Then you have boxers like Eubank Jr holding onto muck like the IBO super-middleweight title and claiming to be a world champion (in a division with no less than four other 'world champions'! WBA Regular and Super champion - Really??) This goes on in every weight class (of which - again - there are too many!)
The alphabet belts made the sport a bit of a joke long before the current run of match-ups - I mean, before Mayweather v McGregor we had Ali v Inoki (and Balboa v Thunder Lips!) And while we are on McGregor; the UFC certainly have it right with one champion per weight class.
AJ is doing what he can for heavyweight boxing in this country, he's the only boxer we have with real star potential. But outside of him, the only other boxer whose career I'm interested in right now is Vasyl Lomachenko. That guy brings something different with a tremendous work rate, outstanding movement and a desire to keep stepping up.
If they won't do away with all the sanctioning bodies, then it has to be intriguing match-ups that keep the sport going. If I had a say in it, I'd be looking to put together something like the Super Six again.
