The ufc has 500 fighters, let's not pretend that the majority of them are elite. He took the spot of someone that beat up a few part time fighters on a regional circuit? Oh no!
Look, he isn't taking anything from anyone, the only way that would be true is if they gave him a title fight right away.
And there is a big difference between punk coming in and taking the spot of a cody McKenzie level fighter and Brock and the rock going back to the wwe and headlining the biggest shows.
With 500 fighters, it's not exactly the same as qualifying for the world cup, where it's an accomplishment to do so. For fuck sake, a coffee barista was a co-mainevent, but you know that dude had a 4-0 record and wasn't a pro wrestler, so that's cool.
