Rhythm disrupted by a relentless San Diego pass rush, Roethlisberger struggled early and the Steelers never recovered in a listless — not to mention perplexing — 34-24 loss on Sunday.
“We got whupped,” Pittsburgh linebacker Larry Foote said.
A thumping that continued a maddening trend for the Steelers (7-6), who have won on the road at Baltimore, Cincinnati and the New York Giants this year but also fallen to Tennessee, Oakland, Cleveland and now the Chargers (5-8).
Roethlisberger completed 22 of 42 passes for 285 yards and three touchdowns in his first game back after spraining his right shoulder and dislocating a rib in an overtime win against Kansas City nearly a month ago. Most of the yards and all of the scores came after the Steelers had fallen behind by 24 points to a team that had never won in Pittsburgh during the regular season.
“I have no clue (why we’re inconsistent),” Roethlisberger said. “If I knew I don’t think we’d do it anymore. I thought we’d play better.”
The Steelers thought they’d revived their season last Sunday in an emotional victory over the Ravens behind third-string quarterback Charlie Batch. Instead, they looked disinterested at times and sloppy at others against a team that hardly looked like it was playing out the string.
Philip Rivers threw three touchdown passes, two to Danario Alexander, and underachieving San Diego beat the Steelers on the road for the first time since the AFL and NFL merged more than 40 years ago.
“This isn’t necessarily the team we thought we’d have on the field in December, but this is the type of performance we thought we’d put together,” said Rivers, who completed 21 of 41 passes for 200 yards.
The Chargers have been one of the NFL’s biggest disappointments after a 3-1 start evaporated into a 1-7 slide that fueled speculation coach Norv Turner and general manager A.J. Smith could be fired at season’s end.
