Willis McGhee or Chris johnsson?

[TeamDanimal]

I'm struggling with the decision on this one. After last week and johnsson only getting 11 carries for 4 yards and now this week going up against SD whose rush defense shut down McFadden last week I'm thinking not to play him and play Willis McGhee. Baltimore relied heavily on him last week getting almost all the carries and this week he will be up against the Atlanta rush defense who aren't very good. Thoughts?

Sorry didn't mean to say Baltimore meant to say Denver.

I have mcgahee starting as of right now but I know Chris Johnson can do better just not sure if I can put him in yet while Denver is handing the ball like crazy to Willis mcgahee
