Running a no-huddle, no-hurry offense under new coach Mike McCoy, Rivers gets to the line of scrimmage with roughly 20 seconds left on the play clock, enough time to read the defense and check into a different play, if necessary. It's a luxury he didn't have in Norv Turner's offense.

"I feel in sync. I have a rhythm and I'm comfortable in the pocket when we get that no-huddle going," Rivers said. "It's big being 2-2 instead of 1-3. I know we've been there before but it's tough to dig yourself out of 1-3, especially when you're playing with young guys and guys you didn't expect to be in there. They can gain confidence off games like this."

Rivers completed 35 of 42 passes, his final TD pass, to Gates, being the 200th of his career. He threw two TD passes to running back Danny Woodhead.

After having three 400-yard games in his previous nine seasons, Rivers has two in this year's four games. After 35 interceptions the last two seasons, he's been picked off only twice so far while throwing 11 touchdown passes.

"It was really what he did throughout the ballgame," Dallas coach Jason Garrett said. "He did a fantastic job. He really controlled the football and controlled the game. He did an outstanding job getting them into the right play over and over again.

"He threw the ball as well as he's thrown in a long, long time."

Rivers' biggest pass wasn't necessarily his prettiest. He short-armed one over the middle to Gates, who slid behind linebacker Sean Lee to haul it in and score with 6:54 to go.

Lee had intercepted Rivers on a deflected pass and returned it 52 yards for a 21-10 lead late in the second quarter. Dallas didn't score again.

"We were able to get some looks we thought we could take advantage of," said Gates, who had 10 catches for 136 yards. "The way he threw that ball, he put it in the right place and I was able to make the play."

San Diego's defense came up with a big stop in the final moments. Tony Romo moved the Cowboys to the San Diego 7, where he hit Terrance Williams at the 1. Williams was stretching for the end zone when he was hit by Crezdon Butler and fumbled. San Diego's Richard Marshall recovered for a touchback.

A week earlier, Butler was burned on a 34-yard touchdown pass from Jake Locker to Justin Hunter with 15 seconds to play to give Tennessee a 20-17 victory. Butler was in against the Cowboys because Derek Cox left with a knee injury.

"I saw that the ball was a little loose. We learn as a kid you can put a hit on the ball and it comes out," Butler said. "I had no idea he lost it. Then I rolled over and I saw Marshall had it.

"Last week was tough and I had to move on from that," Butler added. "Being a defensive back you have a short-term memory. I'm glad I made that play today."

It was only the second takeaway of the season for San Diego.

San Diego trailed 21-10 when Nick Novak started the comeback with a 42-yard field goal as the first-half clock expired.

The Chargers took the opening kickoff of the second half and Rivers moved them 80 yards, capping the drive with a 13-yard pass to Woodhead to pull to 21-20.

The way Rivers ran the offense, the Cowboys didn't have a chance to come back. They ran only seven offensive plays in the third quarter.

"That's what we see every day," Woodhead said of Rivers. "He was great, but he's always great."

After forcing Dallas to punt, San Diego took a 23-21 lead on Novak's 23-yard field goal that capped a drive starting from the Chargers 11.

Romo threw touchdown passes of 5 and 34 yards to Dez Bryant in the second quarter, when Dallas scored 21 points.

Lee got his interception return for a TD when Rivers was hit by tackle Jason Hatcher as he released the ball.
