One must believe Shanahan didn't bring Travis Henry to Denver to play partial starter in his system. Henry will be the starter, but I would look for Mike Bell to spell him often, most likely 3rd down (if they've got more than 5 yards to go). I don't see this being a RBBC like it was last year. As long as Mike doesn't run Henry into the ground he should certainly clear, at least 1,300 yards.
