The Titans were outplayed in virtually every area of the game, but no area stuck out more than the failure of the Titans defense to get off the field on third down.
As a result, Tennessee allowed 27 first downs to the Chargers, while the Titans managed a pathetic nine first downs.
This led to a tired defense in the second half of the game, and that's when the Chargers really stomped the throats of the Titans and pulled away.
Allowing an opponent to convert 10 third downs is asking for trouble later in the game.
A third-down conversion less than a minute into the game by the Chargers really set the tone for how they were going to attack this young Titans defense.
Philip Rivers was able to check down to Ronnie Brown for a simple seven-yard gain for a first down, and the Chargers would end up making this a theme that the Titans just couldn't figure out.
Even when the Titans were able to make tackles for loss against San Diego's run game, somehow the underneath throws seemed to always bail out the Chargers and extend drives.
Will Witherspoon got burned badly on these plays all day.
The fact that Colin McCarthy was out of the game really played a significant part in the Titans looking so lost on these underneath throws and crossing routes.
It wasn't just the underneath throws that hurt the Titans defense. The San Diego tight ends continued to give the Tennessee headaches, despite Antonio Gates being absent.
The biggest example of this was the scoring play to Dante Rosario that made it 31-10. Witherspoon bit on the play-action fake by Rivers, and the rest was history.
That was a common theme that helped lead to 38 points for the Chargers.
No matter who the opposing tight ends seem to be, they always have big days against the Titans secondary.
When head coach Mike Munchak goes back to this pathetic game tape, I'm sure cleaning up the defense on third downs will be his top priority.
