One never quite knows what Shanahan's gonna do, making every Denver RB move a roll of the dice.
I think he wanted Bell to step up and take the job, but instead is butting heads with the youngster. Then he probably wanted Griffin to grab it and run with it (because Droughns, as mentioned above, provides value to the team in a returner/FB role). Hearst was nothing but insurance, and clearly isn't part of the picture.
My take: Q, if healthy, starts this weekend in what amounts to an audition for the No. 1 RB gig, with Droughns stepping in on short-yardage and goal-line stuff. Now, if Q succeeds and doesn't put the ball on the ground, he's back in action. If it goes poorly, then Shanny can make the switch to Droughns on merit without having to face media inquiry about Q losing his job because of injury. Bell lurks in the background, with a miraculous positive attitude change at midseason not beyond the realm of possibility.
Just my two coins, of course.
