These close calls could very likely keep San Diego out of the playoffs.
Couple the Chargers' loss in Pittsburgh on Sunday with Denver's victory in Atlanta and the Chargers are now two games behind Denver in the AFC West race with six games to go. Yes, they are running out of time.
San Diego played decently against the Steelers, and it could have easily won the bad weather game. San Diego's defense made good improvement and was much more aggressive than it was earlier in the season.
But the Chargers' biggest problem is that these close calls are going the other way. It is the third San Diego loss in the final minute of the game. In the first two weeks of the season, against Carolina and Denver, San Diego lost in a similar fashion.
Mix San Diego's overall inconsistency with the last-minute failures and it's no surprise that the Chargers are floundering at 4-6. The preseason Super Bowl favorite may simply be running out of time.
