he subbed a 'black belt'
Filho was wacked out on drugs. While it looked really good on the resume at the time, it was like he had entered the cage already defeated.
I agree with Pwent that his Anderson loss was his most impressive. My mouth hit the floor as Shael molested Anderson. Scored a couple of those rounds 10-8.
As far as win goes....probably Shogun, overall but the Nasty Nate and Okami wins were incredibly solid, as those guys were something like the number 1 and 2 contenders.
Marquardts only real loss in like the previous 5 years was Anderson. He had a BS split loss to Leites but had just KO'd Maia. Could make a case for that as Chaels best win.
He beat Oleynik too.
