The situation is about to get ugly. If Bennett can ever get healthy I see no reason why they'll pamper him. Clearly the backups are just as effective. Mewelde having a solid week will earn him more PT and we all know that a healthy Moe Williams will get some touches.
With every RB they play kicking butt I would be leery of relying on OSmith (and alienating Bennett) when OS is such a risk to get a major suspension for off the field issues (he had these issues all through college as well).
Evil will always triumph because good is dumb.
