Having to rely on Palmer & Smith in qb-points heavy league might hurt you. I like Palmer, but not as my #1 this year. Nice receiver depth.
I don't think there is anything wrong with Carson as your starting QB. He is going to have a big year i think, he has a ton of weapons and the Bengals also have a running game. I would probably start Steve Smith ahead of Ochocinco though, and you need another WR i think.
