I like the idea of dumping FWP and Caddy, but I think you might be able to get a little bit more in return. Last I heard Caddy has knee issues again, so I would try to sell high on him.
Even if the other owner doesn't budge, I still think I'd do it. Looks like you'll probably start your 2nd RB based on matchups anyway, and I like the potential of Bradshaw/Leon over FWP/Caddy.
Good luck, and please see mine:viewtopic.php?t=449803
