Referee stoppages are too open to the opinion of the ref, too many grey areas. "Intelligently defending your self" or my favourite "can you continue". Yeah ask the person you suspect of brain trauma if they have brain trauma. I think we need some thing a bit more specific to determine the winner of these fights. These days if it's not a clear, plain as day knockout or submission, You never know who is going to win. To be honest I'm sick of the controversy! Thoughts?
