Bush for Benson?

[blackvaultcm]

who has greater potential the rest of season? (Standard scoring league, no PPR)
I am already deep on RB position (Rice, Richardson, RIdley, Sproles, Bradshaw, so its not like im desperate, but if its an upgrade or greater potential outlook please advise.

Guy offered Benson for Bush (he does have Forte).

THank you

Bush has more value. I don't really trust Benson. Bush will be good with or without Forte taking the touches from him. He's just good.
