I am in a 12 team ppr league where we start 2 RB, 2 WR, and 1 Flex.  I am looking to upgrade my receivers and I made the following trade offer Jamal Lewis for Hines Ward.  He countered with Bernard Berrian for Lewis.  My team is as follows:

RB: Westbrook, Kevin Smith, Addai, Lewis
WR: Santana Moss, Greg Camarillo, Roy Williams, Torry Holt

I have been playing Kevin Smith in the flex and has continued to put up decent points every week and seems to be their main offensive weapon in addition to Calvin Johnson.  I am not sure if Berrian is worth the trade to me.  Any thoughts would be much appreciated.  Thanks.

I wouldn't make that trade, Berrian is just too spotty a player for my liking.  At least with Lewis you know he'll get his touches and some points for you.
