What was the last team to miss the NFL playoffs as good as SD?

Seriously...looking at the schedule, it's difficult to see the Chargers making the playoffs. But they are a REALLY good football team (and I'm not just basing this on beating the Colts).

Edit to add:
Even while playing one of the toughest schedules in football, the Chargers have:
5 losses by an average of 2.8 points/loss
9 wins by an average of 16.55 points/win

The Chargers have lost some heartbreakers and have played an absolutely grueling schedule -- this combined with the relative ease of Jacksonville and Pittsburgh's schedules will likely work to cause SD to miss the playoffs.

But at this point in the season, I'd say the Chargers are easily a top 5 team in the entire league. Only the Seahawks are better than SD from the NFC...and only the Colts and (maybe) the Bengals and Broncos are better than them in the AFC...IMO.

So -- when was the last time a team this good didn't make the dance?
