B Jax/Jones/Knox/Buckhalter W/R Flex

[TheBurnerTurner]

Having a bit of a dilemma at my flex position this week.

Standard 12 man no ppr league, 2 flex spots. Right now I'm deciding between Brandon Jackson, Johnny Knox, Buckhalter, and Derrick Mason for those two spots. Leaning towards Knox and Buckhalter, but I can't make up my mind

Who should get the start?

Buckhalter and knox, if you're someone that loves RBs I guess B. Jackson can be a play as well, but with the bears and packs playing i'm thinking shoot out through the air as the Bears are awesome against the run.
