The Pittsburgh Steelers have a chance to clinch the division this week. It could happen as early as Saturday, as the Ravens' losing to the Packers would clinch the division for Pittsburgh. Likewise, the Steelers just need to beat the Browns in order to lock in their playoff spot.
No matter what happens on Saturday, I would expect the starters to at least begin the game on Sunday. However, if the division is figured out by the end of this weekend, resting starters in week 18 will be a no-brainer.
For two Steelers rookies, this would be a make-or-break opportunity.
