Offerred a trade and need advice

[Hardcore Texan]

Got offered both of these trades today by the same guy:

Get:
Breaston, Steve WR ARI
Lynch, Marshawn RB BUF
Williams, Ricky RB MIA

Give up:
Michael Turner

-----------------

Get:
Hines Ward
Ricky Williams

Give up:
Michael Turner

------------------

I am not sure what to think about these, Turner has been okay, he has a pretty favorable schedule coming up and he is my best back so I am tempted to just keep him, I really could use a WR like Ward though. Here's the rest of my team:

QB
A Rodgers
J Flacco

RB
J Lewis
M Turner
C Portis
J Charles

WR
D Jackson
L Evans
S Moss
P Harvin

TE
J Carlson
H Miller

K - L Tynes

D/ST - Jets

As you can see, not a very strong team, it's OK but that's about it based on how these guys have produced. I am just not particularly strong at RB or WR. Don't even remember how I got here, goo thing my other team is 6-2.
