NEED ADVICE ON A TRADE PLEASE

I was offered B. Marshall and Cadillac Williams for Pierre Thomas and Percy Harvin. The league format is 2 RBs, 3 WRs, No Flex. I have AP and Turner so Thomas rides pine mostly. My WRs are Andre Johnson, Megatron, Burleson, Percy, Gage and Coles. What do I do? Will Marshall be productive enough for me? I'm thinking he would fit in nicely with Andre and Calvin. Or Andre and Nate (since Megatron has been hurt). What do you think?

Thanks for your comments/help in advance!

well you are stacked in the rb department so giving away pierro is no hit,,, marshall will continue to be productive but not so high on cadillac

i think the trade will benefit ur team

no deal

thomas is a nice handcuff and caddy sucks imo. you have security with thomas, plus you do have depth at WR. Dark horse imo is Coles, now with Henry out, he will get more looks. marshall can be awesome, but I'd try and trade two wr for him.
