So they say they'll fight each other, but then A announces he'll fight Z and B says he'll fight Y. And then if they both win, A will fight X and B will fight W. And if they win those, then and only then will A fight B. It gives the stars two easy wins and lines the pocket of the promoter with television money for what are non-competitive fights. But it's a problem that has plagued boxing for years. Promoters will tell you they need to build up a fight, and while there is a sliver of truth to it, if they did a better job of promoting and making the competitive fights all the time, it wouldn't be nearly as necessary.
