The last few UFC pay per views had preliminary fights air live before the PpV started. Hope they do it again. Every now and then you a live fight night or Full ufc card on spike. But yes 99% of it is reruns. I use to be a boxing freak.
The difference for me is I can enjoy nearly any professional MMA fight. Boxing is at a point where I can only get into the elite (manny, floyd, etc.) matchups.
