Admittedly, this is the problem with boxing. There are like ten guys that are well known and so few marquee match ups. By UFC consolidating all the fighters under one roof, marketing them, stacking cards, they were really able to pull ahead of boxing. Crawford, Loma, Riggy, even GGG to an extent, all lack these marquee match up wins. Every time I see Loma or Crawford fighting, I always say "who da cook is dat guy?". And the craziest thing is, they all have these 30-0 records but chock full of guys with no Wikipedia pages. Indongo may be go may be a much better fighter than Poirier, but I guarantee you more people know who Dustin Poirier is.
There are just too many promoters, too much bureaucracy, too many belts and then mediocre mandatory title matches for all their belts if they want to keep their belts.
Obviously, the upside to being all under one stable is increased visibility and fans buying your match ups, but the downside is you run the risk of getting hosed over, like the UFC does to it's fighters.
