"We can always get better," Brees said. "We're the third-highest scoring offense in the league and we want to be first. We're top 10 in red zone and third downs but we want to be No. 1. You look at those things and there is always room for improvement."
The Chargers feature the NFL's top-ranked rush defense, but it's been their revved-up offense that has them primed to make a run for another playoff berth. With Brees coming close to last year's Pro Bowl season on a unit that includes Pro Bowlers LaDainian Tomlinson and Antonio Gates, it's easy to see why the offense is so high-powered.
Brees and Co. have scored at least 27 points five times this season and twice have sped past the 40-point mark. In the past two games, victories over the Chiefs and Jets, the Chargers averaged nearly 30 points per game.
But Brees, who is 173-for-269 for 2,099 yards and 14 touchdowns, looks at the team's minus-three takeaway/giveaway differential and scratches his head. The offense has turned the ball over 14 times, eight on Brees interceptions.
"We are scoring a lot of points but it makes you wonder how many more points we would have scored," said Brees, who Sunday faces a Bills defense that restricted the high-octane Chiefs to three points last Sunday. "The offense is saying we can't turn the ball over the way we are.
"Shoot, interceptions are going to happen now and then, that is just the way it is. But I think what you do is you eliminate the bad-decision interceptions. You don't want to have any of those. It's a mental thing all the way."
