It is one of the detriments to playing in America's finest city. Sunny all the time becomes an obstacle when the weather plays a factor in the game.
LaDainian Tomlinson is best when it is dry and he can use his trademark cutting ability to make plays. Tomlinson had 70 first half yards before the rain hit and was barely used in the second half.
Of course, it didn't help that the Chargers held the ball for ten minutes of a possible 30 in the second half.
The offensive line has been slow to adjust to insecure footing and allowed a season-high six sacks on Saturday.
And over the last two weeks, the defense allowed more rushing yards in each game than any other game this year, giving up a season-high 157 on Saturday with 136 coming in the rain-soaked second half.
This was also an offense that had scored 17 points or more in 27 straight games. They managed 14 points total over the last two games.
"Maybe it is playing on two sloppy fields," Tomlinson began. "I don't know. To put up seven points two straight weeks is disappointing to me."
There is a correlation here. The Chargers don't know how to play in hostile conditions that relate to weather. While they won several games last year in severe conditions, they did not play teams with the talent level that they faced this year.
There is simply no way to emulate the erratic nature the elements cause, specifically when the practice in San Diego where the weatherman has the easiest job on the planet.
Soggy days often affect the mood of people – no one is at their best when the clouds let loose. Everyone has heard that. The Chargers were affected much the same. The fire wasn't visible. The mistakes were.
Schottenheimer downplayed the weather and how each team handled it.
"We both played on the same field," he said. The difference is Denver and Kansas City do it on a more consistent basis and it has shown.
The way to fix it is with attitude. The Chargers had that attitude a year ago. They did not come close to having it this year.
"Losing three of the last four – where we go from here, I don't know," Tomlinson wondered. "We need to have a gut check.
"We weren't good enough."
