[JerseyBearsGuy]

Hey all, please help!!!
Ok, so I just got offered Benson, I have to give up kevin SMith & J. Cotchery though.
Its a PPR league, 20 yds=1pt, bonus @ 100 yds. and my roster will look like this.

Brees
R. Brown
Benson
Fitz
Sims-Walker
Ward
Miller
Longwell
Giants

Reserves...
L. Maroney
J. Lewis
Donald Brown
M. Bell
J. Knox-my only wr backup right now.
I have some depth at RB but not great and no depth at WR but Knox .
Looking ahead at scheduels, and everything else, is this a trade I have to make?

Please let a link to HIR...
