It looked to me that the ref (was it matagazzi?) was going in to stop the fight, and then decided to NOT stop it (which i agree woulda been an early stoppage) pulled up and knew he hadda do something to explain his interference, so he took a point for back of the head hitting....
I think the refs original intent on his action was to stop the fight....
I think Mir was lucky in cinching that heel hook cause Lesnar (as gay as his hammerfists are) was beating the crap outta him...
I'd like to see a Lesnar/Crocop or Arlovski or Kongo match.... dude showed he is a beast and with a little time will dominate
