Trying to trade Portis?

I'm trying to trade Clinton Portis in my fantasy football pool for a decent wide out as behind fitz i have very little substance and my rb depth is pretty solid(not to mention portis' lackluster play hasn't exactly helped me) I offered him up for moss and jennings in seperate deals, but was as expected rejected by both owners. More realistically who should I be trying to grab? (My other wide outs that I already have are Bowe, Evans, Hester and my other RB's are Thomas, Grant, Rice and Smith)
