on UFC Undisputed 2010.
I simulated 10 fights. Carwin won 6 by spectastic KO, 1 by Kimura (seriously).
Brock won 2 via GNP KO, 1 GNP stoppage.
You may deem this a result attained through the use of random number generators, ala Deadliest Warrior. I counter that with "Fuck you! Lesnar sucks!".
Congratulations Mr. Carwin. You are the undisputed UFC HW champion 70% of the time.
Do 100 matches and let me know. Possibly even a thousand. I like to see more accurate results.
