you do realize he is 20+ years into his UFC career and has over 50 fights right? He shouldn't even be here, but he's still competing and winning. He was starting to turn things in his favor prior to getting tapped there, so I don't think he is done.
He's obviously not going to be champ but he isn't completely done and is very okay fighting lower level guys to get a big paycheck.
Not too many fighters deserve it, but, Andrei has put in enough work throughout the years that if he wants to fight low level bums until he retires in the UFC, he should be allowed to.
