Okay all this time I was thinking JDS until I simmed this fight on UFC 3. And the result was so realistic I was like oh snap that could legit happened.
So what happened is JDS was of course owning on the feet and rocked Mir, got Mir down and attempting to finish him. BUT in Mir fashion he found the slightest of smallest openings and was able to lock in an armbar and JDS tapped.
I'm picking Mir. All Mir needs is just one small slip up on the ground and its tap or snap.
