OK so I'm sort of new to fantasy football (it's my first year playing).

I have posted my roster and stuff elsewhere but I just received a trade offer and I'm in need of some advice.

League info:

12 team league

6 pts for all TDs
1 pt for 20 passing yds
1 pts for every 10 rushing/ receiving yds

After the jump is the trade offer

Here is my roster:

Starters:
QB: Aaron Rodgers
RB1: DeAngelo Williams
RB2: Steve Slaton
RB/WR: Anthony Gonzalez
WR1: Roy E. Williams
WR2: Eddie Royal
TE: Dustin Keller
D/ST: Giants
K: David Akers

Bench:
QB: Matt Hasselbeck
RB: Ray Rice
RB: Shonn Greene
WR: Jericho Cotchery
WR: Laveranues Coles
TE: Vernon Davis
RB: Glenn Cofee

Here is the other guy's roster:

Starters:

QB: Tom Brady
RB: Willie Parker
RB Cedric Benson
RB/WR: Darren Sproles
WR: Greg Jennings
WR: Terrell Owens
TE: Greg Olsen
D/ST: Eagles
K: Stephen Gostkowski

Bench

QB: Carson Palmer
WR: Chris Henry
D/ST: Bears
RB: Mewelde Moore
TE Anthony Fasano
RB: Ricky Williams
QB: Jason Campbell

I have been offered Greg Jennings for DeAngelo Williams.

My first thoughts were:

This guy is nuts, RBs that catch and run put up more points than WRs

DeAngelo Williams is projected to put up 232 pts this season
Greg Jennings is projected to put up 190 pts this season

Plus he is extremely WEAK at RB (he's more weak at RB than I am at WR)

So, I am interested in picking up Jennings....but I want a more balanced trade.

Thoughts?
