SAN DIEGO — Philip Rivers likes to yap.

Shawne Merriman likes to dance.

Igor Olshansky gave the undefeated New England Patriots some billboard material, as if they needed any outside help in advance of the AFC championship game.

Have the San Diego Chargers simply regained their swagger, or have they become cocky trash-talkers?

Well, maybe ask Olshansky.

"Who? New England?" the defensive end said after the Chargers upset the Indianapolis Colts 28-24 on Sunday. "Seriously, I mean, they're more worried than we are, I promise you. Believe me. They know what's up.

"The way that we're playing now, nothing can stop us," he added.

Coach Norv Turner had words with Olshansky about his choice of words.

"I addressed that on Monday and I think in a weak moment Igor misspoke. I think our guys have handled this deal really well and we're just getting ready to play," Turner said.

Then there's Rivers, whose mouth seems to be making as much news as his injured right knee.

San Diego's quarterback has been caught on camera this year yapping at fans and opposing players.

On Sunday, Rivers had two exchanges with fans. When he was walking to the locker room for treatment, he could be seen telling someone, "I'll be back." Then, when Peyton Manning's final pass of the game fell incomplete, Rivers turned and was talking to fans behind the bench.

During a Christmas Eve win over division rival Denver, cameras caught the QB and teammates Shaun Phillips and Matt Wilhelm having an animated conversation with Broncos quarterback Jay Cutler.

Rivers has become a flashpoint, particularly on talk radio.

"I'm aware of it," Rivers said. "I really don't get too caught up in it. It's kind of surprising, really, to be honest with you. But, again, I'm out there having a good time as I did in the backyard since I was 5 years old. I'm not saying anything out of line."
