Would you trade Randy Moss/CJ Spiller for Mendenhall/Crabtree?

Don't do it. CJ could turn out being this years Jamaal Charles. Moss and Crabtree aren't even on the same page as Denny stated above. But if you look at numbers, you're good at RB by far, so you don't need Mendenhall. And for WR, you shouldn't get rid of Moss.
