I'm in a keeper league on espn.com that runs by the standard rules (no PPR).  My RB's are AP and  Mendenhall (along with Ryan Mathews, Fred Jackson and Marion Barber for depth options) and just today I was offered a trade for Mendenhall.  The proposal was Randy Moss and Ricky Williams for Mendenhall in an unbalanced trade.  I quickly put down the thought of getting those two players for one of my best players, but it got me wondering... what exactly is Mendenhall's trade value.  I guess it comes down to what happens when Big Ben comes back next week and how the offense is adapted.  I guess my question to everyone would be if you were in my situation and had these 2 guys @ RB, and you were to consider moving Mendenhall (and I'm not saying I'm really considering it at all) what would you be asking for in return?
