Trade: Bowe and Lynch for R. Moss and C. Williams

Hey so I just got offered this trade as a counter to Bowe for Moss straight up. I am tempted but it leaves me really thin at RB. The rest of my team is:

• QB Rivers
• RB Foster, LT, Stewart, Ward
• WR Nicks, Jennings, Garcon, M. Williams (TB)
• TE Cooley, Heap

What do you guys think? is Moss worth giving up Bowe and Lynch
