Should we rest starters ?

If we lose, the 49ers lose and the Packers lose, we not only screw our selves out of a 1 seed but open up the 3 way tie again (us, Seattle, GB) and put ourselves back into the 3rd seed.

I'm on the record of having little faith in the battered Lions but if they get an any given Sunday win I want it to be a celebration and not have a chance to screw us even if Seattle wins.
