He's nothing special. He was pretty selective in the hands he played all throughout the Main Event and TOC, and it doesn't look like it's even possible for him to have a Matusow blowup. He's good at handling himself at the table.
Maybe this is a spoiler...
In the TOC did you guys see the hand where he had KK and really took his time with it? He showed respect to the raises and thought about someone having aces. He didn't make a rash, quick call. In the end he made the right call and knocked out both players. Both were holding AQ[end]
He won't have a professional career or anything, but I don't mind watching him play (with Mute on of course
, man he's a talker)
