It has evolved. For one we have the 10 point must scoring system which actually made knockdowns count for something. I've seen on boxrec before fighters who have been down 5 times throughout a bout in the old days but still won the majority of rounds and the decision.

That's been one key, obviously all the rule changes most notably the changing of how many rounds which I think ultimately is a good thing. There is replay in New Jersey like they mentioned on the broadcast but I haven't seen it used yet.

I hope they can show replays better then ESPN does though because it seems I am always waiting for hours to get a replay there. Literally I don't know if it's intentional but it takes forever there.
