I don't understand
You don't like cages because Manhoef got caught tangled up in the corner of a ring? I don't see the logic of that.
I am not sure that the corner was the reason this fight went the way it did, either. Manhoef wasn't looking like a winner off his back regardless. I don't think he would have been in trouble whether the end of the fight took place in the middle of the ring or in the corner.
