Well we should still beat Detroit. Then we need to hope 1 win out of the last 3 games will be enough (Chicago and Green Bay must both lose at least 1 game).
I think we can still beat Arizona. Hightower has averaged 2.0 yards per carry in the last 4 games, which means 2 things: 1, their run offense sucks, and 2, they've had to heavily rely on their pass offense the last 4 games, with medoicre success (2-2, including close games against SF and Sea). So airing it out against The Vikings is not necessarily the perfect recipe.
To me, the most important thing about the suspensions is not the run defense, but can we still get pressure on the quarterback? Can Allen continue to create pressue while being double teamed? Can Robison and Edwards step up their play?
