Who to start at RB2 today? Lynch, Bradshaw, Brown?

I've got Marshawn Lynch, Ahmad Bradshaw, and Donald Brown as options at RB2. I've already got Chris Johnson at RB1, and my usual RB2(Marion Barber) is on a Bye. Let me know who. If you toss in a reason for who and why, I'll give you a thumbs up and probably Best Answer, too. Thanks to anyone that takes the time to answer.
