You've already seen the one I was going to mention lol.
It's hard to believe what happened to Mark Kerr all those years ago. Dude was a destroyer and now he's nothing and has been for a long time.
I think I'm going to check out that Renzo Gracie one tonight though. If I can find it.
EDIT: Just checked out the Renzo one and I didn't like it nearly as much as the Smashing Machine.
