You don't know how tough or how easy your schedule is until the season plays out. A year ago at this time, Dallas was supposed to have the 11th toughest schedule in 2012. But that was based on the opponents' 2011 W-L records.
It ended up being the 5th toughest schedule. A year ago, the Steelers were supposed to have the 14th toughest schedule in 2012. It ended up being the 6th easiest. That's why the Steelers (also 8-8) will get to pick ahead of us in the draft.
