Did the UFC make the right move firing Mayhem Miller?

Two fights in the UFC and Jason "Mayhem" Miller proved once again that his bark is bigger than his bite. After comming off an embarrasing loss to Michael Bisping in December, UFC president Dana White was less than enthusiastic about giving him another fight. He did however because of his popularity and markability. "Mayhem" did alot of trash talking in this fight against CB Dollaway as well. He even went far enough to say that he would retire if he lost to him. He did say however that losing to him was unimaginable in the first place. Well the unimaginable just happened and CB Dollaway had the last laugh... dominating Miller for 3 rounds. A frustrated crowd booed Mayhem Miller for his second straight pitiful performance. Dana White was less than thrilled with Millers performance and his tweet said it all "THAT SUCKED!!". Now a 2 loss streak isnt usually enough to cut a UFC fighter, and Miller seemed to be suffering a knee injury throughout the fight. If the knee injury is significant im sure itll change fans view the fight. But Dana White said that his one sided loss was hardly the reason. That an incident backstage happened. He wouldn't elebarate on what it was but he called it some "crazy bullshit" and said that it wasnt physical. Dana White also thinks that Miller should own up to his pre fight promise, and admitted that he was never a fan of his crazy antics, his flashy entrances and just him being a "clown" in general. Is "Uncle Dana" being reasonable or should have he given him another chance. I have mixed feelings on this fight. If his knee was really bothering him that bad, I give Miller credit for continuing. But after two embarrasing losses maybe he should be cut.. losing to Bisping was one thing but Dollaway was a gimme for him. He looked nearly as awful against Dollaway. As far as the outcome goes I have mixed reaction as well. Im glad that CB Dollaway had the last laugh. Miller really underestimated him and talked alot of trash saying hes a nobody and doesn't deserve to fight him. Dollaway didn't respond back, didn't trash talk and trained his ass off. He had the last laugh. Good for him and in a way serves Miller right, he out of all people has no right to talk trash. I do feel bad for Miller though. He's an exciting fighter and a fan favorite. It's a shame to see him go like this. It's very odd too. This was a guy who submitted Robbie Lawler, beat Denis Kang and had a good fight against Jake Shields in a Strikeforce title shot. Maybe he just doesnt have the mentallity to fight at the big stage. Whether Mayhem Miller owns up to his pre fight promise or not, Dana White handed him a pink slip regardless and hes done in the UFC at least. Was he right or was he wrong?
