leg stomps (which is what Yoel injured him with in the first fight) should be banned, they can do the equivalent damage of a kneebar without giving the opponent a chance to tap, its unfair and can sideline fighters for years out of their career. Before any moron say "but in an armbar.."--you can tap out before your arm is broken, you can't tap out of a kick as it's landing and avoid having your ACL/MCL torn. Targetting the knee is bad for the sport, kicks should have to be well above or below it, not close enough to hyperextend it.
