Obviously, this could go on and on, we all have our opinions. The UFC fights entertained you, that's all that matters. I enjoy sports, I like watching them, but I also take them with a grain of salt because have no idea what kind of back room hand shakes are going on. Fixing games and fights has gone on before, I don't see it outside the realm of possibility, especially when noticing small ironies. That's my opinion...take it or leave it.
BTW...the other fight you mentioned are relatively big names as well...so yes, I would lump them in with Brock.
