I don't think Ozzy could pull a Rob. A smart team will keep him as far as the merge because he'll win them challenges, but then get rid of him asap for the same reason. I don't remember his social game being particularly good.
Coach surprises me as I thought his second time around he'd gone all zen about the whole thing and was at peace with it. He was a different player his first two times out, so who knows what we'd get this time.
Both these guys have played twice before - if they're going to make this truly about "redemption" shouldn't it be someone who has played once and for whatever reason didn't go as far as they might have? I still like the idea of someone like Mike from Australia, who was injured and thus didn't fulfill his potential in the game. I didn't mind Stephanie the first time she came back, as it seemed so clear she'd lucked out with a useless tribe and things would have been much different for her in other circumstances - but then she was indeed redeemed that time as she got to play the full game.
And someone's going to criticize them if it's indeed four men who have been brought back in this era of redemption, and no women.
