Brown is an inconsistent fighter. I don't know if he's going to stretch that winning streak past this fight. Mien managed to put Dan Miller away who had never been finished at Middleweight after facing guys like Paul Harris, Marquart, Bisping, and Maia.
I think Mein takes this by decision. Brown is a tough guy who won't quit, but Mien seems to be smart enough to not get into a brawl.
