I am in a standard 10 team money league and I am currently in first place at 6-2.

I have the following team:

QB: Stafford
RB: Rice
RB: Fred Jackson
WR: Boldin
WR: Colston
RB/WR: Forte
TE: Keller
K: Hanson
DEF: DET

Bench:
Legarret Blount
Michael Bush
Malcolm Floyd
Cassel
Raiders DEF

I try and lowball this guy and offered him Blount and Colston for Calvin...but he countered me and asked for Forte and Colston. What do you all think? I would still have two stud RB's with Rice and Jackson and with Blount the primary back in Tampa I think I should pull the trigger. But because I am a Lions homer....I wanted to get other opinions.
