IMO Mir takes this UD or TKO 9/10 times, staph or not.
I think that mir is smart enough to know that going to the ground with nog isnt going to get him anywhere, but even if it did go to the ground I think mirs jiu jitsu would be good enough to avoid submissions until he was back on his feet.
That along with the fact that IMO mirs striking is far more effective than nogs, I dont think it matters how many times they fight, mir is a bad matchup for nog.
