MIAMI – Winless Miami against unbeaten New England is more than worst versus first. The standings suggest it’s the NFL’s biggest mismatch since Dan Marino was flinging touchdown passes at a record rate.Oddsmakers certainly see it as lopsided. The Patriots are favored by a whopping 161/2 points even though they’re on the road.The last time a team 6-0 or better played a team 0-6 or worse was in 1984, according to the Elias Sports Bureau. And the game involved the Dolphins – they improved to 9-0 with a 38-7 win over the Buffalo Bills, who fell to 0-9. Marino threw three touchdown passes on the way to a season total of 48, then an NFL record.Now it’s the Patriots with the hotshot quarterback. Tom Brady is on a record pace with 21 touchdown passes and only two interceptions, an astounding ratio that’s a big factor in New England’s 6-0 start.The Dolphins are 0-6 and already thinking beyond this season. They traded leading receiver Chris Chambers to San Diego on Tuesday for a second-round draft pick in 2008.”We all have to realize we’re not sitting here 6-0, 4-2, 3-3,” first-year coach Cam Cameron said. “We’re got a lot of work to do.”All of which suggests the Dolphins are ripe for a rout.Naturally, New England coach Bill Belichick’s not buying it.”They’re not 0-6 against us,” he said. “They’ve been in every game. They’re a good team.”Belichick deserves a penalty for improper use of the word “good,” but it’s true the Dolphins aren’t quite as awful as their record suggests. Three times they’ve lost by three points, including once in overtime. Their offense is improving, and running back Ronnie Brown leads the league in yards from scrimmage with 882.”He’s the best player I’ve seen this year offensively,” Belichick said.So the Patriots have a little reason to worry, especially because South Florida seems to bring out their worst.The subtropical climate may be one reason. In September and October, the Patriots are 1-13 in Miami. Since the start of the 1999 season, New England is 2-5 in South Florida and 99-42 everywhere else. The meltdowns in Miami include a 21-0 loss last year and a 29-28 defeat in 2004, when the Patriots came into the game 12-1 and the Dolphins were 2-11.”We haven’t done anything against them,” Belichick said. “There’s nothing for us to be overconfident about.”There’s not much for the Dolphins to be confident about, either.New England has won every game by at least 17 points, matching an NFL record to start a season, and leads the league with an average of 38 points per game. Miami is allowing 30 points per game.
