Need a WR - trade help

Here's my team:
Start 1 QB, 3 WR, 2 RB, 1 TE
PPR league


Qb - Schaub, Orton
WR - Harvin, Marshall, Royal, Maclin
RB - Rice, Charles, Hillis, Torain
TE - Z. Miller, A. Hernandez

Royal is on a bye...Harvin may not play so I'm gonna have to drop someone or trade to get another wr. I've had a few offers for Hillis.

1) Lance Moore
2) Steve Breaston and Michael Crabtree (only have room for one unless I drop someone else)
3) Marshawn Lynch and Mike Williams(TB)

3 is out...don't like it. Sucks to trade someone for lower value, so not sure what to do if Harvin is out. Thoughts?
