There really are no stakes behind it, as it's basically some consolation prize disputed between two opponents picked based on superstardom, entertainment value, and on the fact that neither holds an actual championship title (at least for now).
But if it's an excuse to make some fabulous, exciting cross-division fights, I'm not against it.
But a couple things: This should not come in the way of actual, genuine title matchups being made. And, also, weight classes do exist, so perhaps this appears to gravitate around 155 and 170...maybe 145 now that Holloway won it, so maybe some guy like O'Malley could move up and fight Holloway for it, meaning that fluidity among weight classes for that title is possible, but certainly limited.
Why not make one for 185-HW (the Baddest Big Motherfucker title) and one for 135-170 (the "regular" BMF title)?
