I was about to point this out.
steeljake, this may come off sounding homerish to you but the Cowboys have been underachieving for over a decade now so not making the playoffs/losing first playoff game should be the norm by now.
A Post-Super Bowl Champion such as your lovely Steelers that have managed to lose the games they were SUPPOSED to win, especially when you consider that this year's team and coaching staff is nearly identical to last year's SUPER BOWL CHAMPIONSHIP roster/staff ... I'm sorry but your homeristic bullshit calling what the Cowboys have been known to do during the last decade as the greatest underachievement only makes your homerism even more glaring when you cannot even admit that your Steelers meltdown during those games that a team one-year removed from WINNING the SUPER BOWL CHAMPIONSHIP without very little changes to the roster/staff/scheme is an even greater UNDERACHIEVEMENT.
The Dallas Cowboys are doing what we thought they'd do. I never pegged them as being a Super Bowl champ and I don't know anybody that did peg them as a Super Bowl invite this season, not especially after getting rid of Terrell Owens. Your definition of "underachievement" needs a rewrite.
