Start Marion Barber Sit Tashard Choice?

All reports say Marion Barber III is going full steam.  As a result, he is a must start against a poor Kansas City Chiefs defenses.   His back-up, Tashard Choice remains a viable option, too.  As mentioned, the Chiefs defense is poor.  Based on this alone, Choice should be good for 50 yards.   If Barber pulls up lame, as he did last week, then Choice could easily double that total.  With the byes, Choice is an excellent option for teams who do not have an easy RB2 to play.
