My only question is why? Doesn't that take away opportunities from the competitors at that division?
They'd have to seek out other mma companies who have a 170lb division. And to my knowledge that would be UFC.
I'd hate to think that a flyweight division would be more important then welterweights. Wouldn't you insteand want to keep the 170lb division, and add a flyweight division? Makes more sense to expand on the opportunities, instead of taking away opportunities in favor of another division.
