I don't approve of getting ahead of ourselves, as no 6-10 team has ever made the playoffs, but here you go.

Thanks a bunch Sundance! :9:

But can somebody explain to me how it is, that even though the Cowboys beat the Falcons head-to-head and they have identical records that the Falcons beat out the Cowboys for a playoff spot?
