 Three games left, one game back for a playoff spot and the San Diego Chargers face their biggest challenge of the season. 

 The Chargers will try to slow down Peyton Manning and the high flying Denver Broncos tonight, a Denver team that is setting all types of NFL offensive records this season. 

 Good news for the Chargers is, the last time they faced the Broncos in week 10 they held Denver to a season low of 397 yards, the bad news is they lost the game 28-20. 

One reason for San Diego’s loss that week was because they could not put the ball in the end zone. Red zone efficiency has been the bolts biggest Achilles heel on the season, scoring 52 percent on their red zone opportunities, while the Broncos score almost 80 percent of the time on their trips. 

Chargers Quarterback Phillip Rivers knows that in order to beat Denver, the team is going to have finish of drives with seven points, instead of three. 

“We have to score Touchdowns. To me if you maintain possession of the ball you still got to end it with points.” River said, adding, “Preferably touchdowns against this team.” 

In the muddled up picture that is the AFC playoffs, San Diego (6-7) is one game behind the Baltimore Ravens (7-6) for the last wild card spot.
