Visiting teams talk bravely, even if they don’t really relish a trip to New England. Or St. Louis. Or Kansas City.

That’s what faces the Tennessee Titans, Carolina Panthers and Indianapolis Colts this weekend. All three must travel to playoff games against rested hosts, who are undefeated at home.

The Patriots (14-2), Rams (12-4) and Chiefs (13-3) had last week off. So did the Philadelphia Eagles (12-4), but they haven’t been nearly as stingy at home.

The Patriots not only were spotless at Gillette Stadium, but since a 38-30 win over Tennessee, they allowed just one touchdown at home in the final six games.

Ignoring history, the Titans claim it’s no big deal.

“We started their streak, so I’m telling the fellows we might as well go up there and end it, you know?” Titans All-Pro linebacker Keith Bulluck said. “They’re a good team, and they haven’t lost at home, so you can’t take anything away from them. But it’s playoff time. You have to call it like it is.”

New England has recent history on its side, though, most notably the snow game two years ago in which the Patriots beat the Oakland Raiders. That game is best known for the “tuck rule” that overturned Tom Brady’s fumble, which would have clinched an Oakland victory. New England won in overtime and went on to win the Super Bowl.

So if it is windy and snowy Saturday night, don’t blame the Patriots if they have flashbacks.

Brady, however, doesn’t make a big thing out of being at home.

“Every team that is in the playoffs has had a successful season, and they are really the best teams,” he said. “Tampa Bay won it last year and they didn’t have home field (for the NFC title game). We won it two years ago, we didn’t have home field (in the AFC championship game). And then Baltimore won it three years ago, they didn’t have home field.

“So having home field is important. I think a bye is more important than that.”

Unlike opportunistic New England, Kansas City wins with a prolific offense and a dangerous return game. Even so, those strengths haven’t been dominant on the road nearly as much as at Arrowhead Stadium.

Coach Dick Vermeil, who also knows firsthand about the Rams’ impressive edge in the Edward Jones Dome — he coached St. Louis to the 1999 NFL title — believes Arrowhead intimidates visitors.

“Sometimes you can feel other teams unravel,” he said. “I know it’s loud. I don’t know if it’s the configuration or how wide the mouths are that are yelling and screaming. Human beings are generating the noise. What they do is eliminate ‘check-with-mes,’ directional changes on the line of scrimmage, they eliminate hard counts.”

Historically, this is the round where home teams are least vulnerable. Since 1990, when the league went to six playoff teams per conference, hosts are 43-9 in the divisional round. Only after the 1995 season did two visitors win second-round playoff games — and one of those was Indianapolis at Kansas City.

That doesn’t bode well for the Chiefs, of course, who Sunday face AP co-MVP Peyton Manning and the Colts.

Nor is it comforting for Kansas City that in 1998, the Chiefs were beaten by Denver in this round. Ominously, the Chiefs were perfect at home in both those seasons, too.
