Many people have a substance abuse problems. Just about everyone has some kind of problem. If that is the criteria for staying in the UFC then no one would get the axe.
Many people are saying he brings it evey fight, but he sure didn't look to me like a guy who brought much at 102 or in the Starnes fight or the Bisbing fight. He isn't the worst fighter in the UFC, but IMO he just lost to a guy who seems to walk into even the simplest of traps laid for him. Rosholt is one of the best credentialed wrestlers to enter MMA and got taken down, I think, twice by Leben.
A guy who wouldn't do anything but run backward and cover up, ala Tito, when Leben would bum rush him with punches. Gimme a break. Leben should have won that fight walking away IMO.
I could care less either way. Like I said, Leben isn't the worst fighter in the UFC. There are plenty of others who deserve the boot before him, but it isn't helping him "addiction" to keep him in the same lifestyle that seems to feed it. He clearly can't handle the celebrity status that comes with the UFC. Maybe he should hang it up, at least until he gets his mind right.
