Trade advice

Alright it's done. Both of us feel uneasy about it but we just did a trade of Rashard Mendenhall, Michael Crabtree, and Cadillac Williams for Wes Welker, Cedric Benson, and Chester Taylor.

I really feel like with Welker and Benson, I have a consistent RB as well as consistent WR. I hate giving up Mendenhall. Absolutely hate it, but I feel like I got good value and made up for a mistake I made in not drafting Welker over Crabtree.

I plan to drop Chester Taylor. Available options as backup RBs are Peyton Hillis, Fred Taylor, Kevin Faulk, Javon Ringer, and Leon Washington.

My RB depth took a bit of a hit losing Cadillac and Mendenhall, but I feel like I gained more with Welker and Benson than I lost. What are your thoughts? Also, what FA would you recommend I go after to make up for the loss of Cadillac?
