M. Bell for RE. Williams, eh?

[BoyNamedSue]

Hey people. He wants M. Bell. I need a solid WR3. Pretty sure he'd give up Williams for Bell. Good trade? I feel like both are gambles for the whole season so....

League: 1QB, 2RB, 1RB/WR, 2WR, 1WR/TE, 1TE, D/ST, 1K, 1P (yeah, I know) also have IDPs, but won't bother you w/ those.
*starting WK2
My Roster:
QBs: *Brady, McNabb, Quinn
WRs: *R. White, H. Ward, *D. Henderson, S. Breaston, T. Holt
RBs: *Jacobs, *D. Ward, M. Bell, *Ro. Brown, L. Johnson
TE: *T. Gonzo, T. Heap, H. Miller (Have 3 for potential trade bait)
K: *D. Akers, J. Reed
D/ST: *PIT, ATL

His WRs: R. E. Williams, Hester, Gage, Stokely, Colston (<-Untouchable)
His RBs: Sproles, Hightower, Slaton, L. White, C. Wells
