SAN DIEGO -- Observed in the locker room after the San Diego Chargers' 30-21 win over the Dallas Cowboys on Sunday.

Fast-talking McCoy: Still wired from the win, San Diego coach Mike McCoy did not take too many breaths in between words at the podium after this one.

So does McCoy always talk that fast?

“My wife tells me, 'yes,' ” McCoy joked. “But I’m a little excited, too, so it’s a good reason to talk fast. ... There’s nothing like winning, so I’ll probably talk fast all night.”

A team-defining win: San Diego quarterback Philip Rivers said Sunday’s win over the Cowboys is the type of victory that can help create an identity for his team. “These are the kind of wins that kind of define your character, your personality, your identity,” he said.

Redemption for Butler: Reserve cornerback Crezdon Butler gave up the winning score against Tennessee last week, a 34-yard touchdown reception by Titans rookie receiver Justin Hunter. Butler redeemed himself on Sunday, forcing Dallas rookie receiver Terrance Williams to cough up the ball at the goal line late in the game to help preserve a win. Butler’s teammate Richard Marshall recovered the fumble.

“It feels good,” Butler said. “Last week was tough, and I had to move on from that. Being a defensive back you have to have a short-term memory, and it was time to move on. I’m glad I made that play today.”

A strong finish: After giving up two fourth-quarter leads in the first three games, the Chargers finally finished strong, scoring 20 unanswered points to put the game away. San Diego linebacker Reggie Walker said his team can build on Sunday’s effort.

“It’s a thing that was kind of being held over our heads, not finishing,” Walker said. “And then we went in there and finally finished a game, which is awesome.”
