The Bills are on tap Sunday, the first of four home games the Chargers feel they need to sweep. The others are against the Dolphins, Raiders and Broncos.
The Chargers' thinking is if they can go four-for-four at Qualcomm Stadium, that allows them to possibly stumble twice on the road in a trifecta of games which feature the Redskins, Colts and Chiefs.
The 5-4 Chargers don't have much room for error. Not after letting four games slip away in the fourth quarter when their defense couldn't hold the leads.
But coach Marty Schottenheimer has coaxed his players into putting that deep into the past. Instead of dwelling on what might have been, he told the team last month to approach the stretch run like a nine-game season. To date, the Chargers are undefeated at 2-0.
The Chargers are also upbeat about a dwindling injury report which had grown during a six-game run which included both Super Bowl participants from last season and three East Coast road trips. The Chargers were missing seven starters in the most recent game, a win over the Jets.
Even LaDainian Tomlinson, who entered his bye as the NFL leader with 15 touchdowns, is revved and rested for a sprint toward a playoff berth. And keeping Tomlinson fresh is no accident.
"You can take a guy like that and you can wear him out if you're not careful,'' said offensive coordinator Cam Cameron, who often takes heat when Tomlinson's touches are restricted. "And I take a lot of pride in knowing we have a special guy and we are not going to abuse him. We got to be smart."
Although they've left little room for error, it would be wise not to count out the Chargers.
