Because they were in different organizations. It was all about who would win, why have two guys that could be matched up with one another not fight for the sake of the talk.....
Well they could fight, since they'd both be in the UFC.
But perhaps the two champs would only fight each other once every few years.
This would shake everything up and make the divisions a lot more exciting imo. No more champs resting on their laurels.
The fact this is making some people so livid, to me, just shows how much more exciting this would be. Just the concept of it has some of you foaming at the mouth.
