Whether or not Chris Leben is struggling with an addiction to pain killers has little to do with whether or not Bisping is going to engage with Miller.
Bisping has never had a lot of power. He's fast and fit, has decent take down defense, but typically his fights are boring and go to a decision.
[tangent]I think Leben is a tragic figure, and I wouldn't be surprised to see more addiction surface over the years. The fighters at that level put themselves through a lot of physical abuse. A few years back, the popular assertion was that MMA was safer than boxing, because of the repeated trauma, standing 8 counts and such found in boxing. While I do believe that head trauma is greatly reduced in MMA, the rest of the body is brutalized over years of intense physical training, and I won't be at all surprised to see more stories like this come to light in the years to come.
It's going to be like in Pro Wrestling. While the contact in pro wrestling is loosely choreographed and predetermined, the damage the athletes do to their bodies isn't, and the subsequent addiction to prescription pain killers is common. Mark my words, as the skill level improves across the board at the elite level of MMA, athletes are going to look for any physical advantage they can get, and we're going to see a lot of Leben's who are popping oxycontin and other pain killers so that they can train through injuries.[/tangent]
Why does Leben only get caught in the UK btw? If there's two fighters in a fight why do people always say that one fighters fights are always boring, surely the other fighters must also be boring or perhaps people only think they are boring.
