I can add 1 player to my team, who should I add?

Of these guys, I would add Lynch for extra depth at RB. You don't need a lot with this team, but he's the RB type that Caroll likes. Ivory had a big game last week, but that was against a soft D and Thomas will be back. He's also an interesting choice though. You don't really need another D, but if you want one the Chargers are slightly outscoring the Giants in standard Yahoo scoring (10.5 to 10.2 pts/game average). The Jets are 9.5 pts/game. None of the QBs really help you team and Hill has a broken arm.
