He can be beat. Not by me though
The best of the best have been beaten in the past. The thing about MMA that is the great equalizer is those small gloves. You make a mistake and get caught, lights out.
There was a time not too long ago when nobody thought Chuck Liddell could be beaten. Or what about Anderson Silva? He is amazing, but he has been beaten.
I think Lesner is good for the UFC. He gives people someone to love or hate depending on where you stand. I wouldn't be shocked to see him fight a couple more guys and if he wins those fights face Fedor.
The new ultimate fighter is coming up and it is going to be nothing but heavyweights so you know Dana is out there looking for competition.
