The Chargers have noticed a dumbed-down Dallas Cowboys offense and a spruced up Tony Romo.

Discussion of those things have brought some raised brows and wide eyes during locker room conversations this week.

“He’s been a lot more protective with the football and making good decisions” linebacker Donald Butler observed.

The Chargers are uneasy about this development. They should be with the troubles they’ve had containing quarterbacks particularly mobile ones.

But do not fret. The Chargers have a plan.

They believe the way to stop the new-and-improved Romo is the same way you stymied the old unpredictable Romo.

“We know that once he’s rattled and what not” said defensive end Corey Liuget “it’s easy to take him out of the game.”

Cool.

But – even if the Chargers had actually been making more than a handful of plays on defense the past two weeks – that’s not as easy against Romo as it used to be.

Much like Philip Rivers -- who as you may have heard in recent years had similar issues with the turnovers -- Romo is getting rid of the ball quicker and being afforded more comfort in the pocket in 2013.

The results through three games: a 72.2 percent completion rate that ranks second in the NFL and six touchdowns to one interception.

Yeah where the assumption was that last week in Nashville would be a respite for a struggling Chargers defense there is no doubt this Sunday will be a challenge for a unit that has been torn apart by quarterbacks who like Romo can move a bit.

The Chargers accomplished their goal of keeping Michael Vick from running in Philadelphia but they did allow him to throw for a career-high 428 yards.

This past Sunday Jake Locker had arguably the best of his 14 career starts passing for 299 yards and a touchdown and running for 68 yards and a score.

Again there is a plan.

“You just got to get after him” linebacker Jarret Johnson said. “Somebody has to defeat a block.”
