I was offered Ray Rice for Wes Welker, straight up.

My current RBs and WRs look like this:

RBs: Demarco Murray, Zac Stacy, Shane Vereen, Pierre Thomas.

WRs: Calvin Johnson, Julio Jones, Torrey Smith, Wes Welker, Marques Colston, Steve Smith, Cecil Shorts

I realized after drafting them, that Johnson and Jones have the same bye week, which is why I kept drafting receivers. It's a PPR league, and although Welker is recovering from a concussion, he could still prove to be extremely valuable. Do I do the trade?
