I'll be a hipster cat and say that I was a big MMA fan waaaaay before all the fan-boys started showing up. The reason real fans hate Brock is because he is slowly bringing about the ruin of a great sport. Before him it was all about respect, discipline, and competition. Now it's all about $$$, disrespect, roids, and 'selling' the fight. This is not the WWE, you filthy poo-lip, take your **** back to the ring.
I could go on and on, but there are maybe 1 out of 100 people who agree with me, so lick my belly button lint.
