Wow, the RB situation is tough. All four will be splitting carries this week. Believe it or not I think I take Choice and Bradshaw there. Choice will give you the better chance for a TD (and what happens if Barber reaggravates the quad injury?!?!?!? exactly! lol). Bradshaw will have a good day because the Giants shouldn't have to pass too much to take down the Chiefs, so once Jacobs scores his TD's, Bradshaw will get a lot of work running out the clock.
As for the WR's, I think Eddie Royal gets back on track this week against Dallas who will probably focus on taking away Marshall. So I'd pick up Eddie Royal there.
**Also I would be catious of Colston this week agaist Derrell Revis, but his probability of getting a TD makes him a must start**
