WR Upgrade

[steakhead]

Should I trade a RB to upgrade my WR's. I'm hoping maybe Portis and Williams have a couple of good games and try to sell high

QB(1) Brady, Palmer
WR(2) R Moss, M Williams(TB), M Wallace, Collie
RB(2) Foster, Bradshaw, B Jackson, C Williams, Portis
W/T(1) Davis
K(1) Kaeding
Def(1) Dallas
