Halftime observations from Saints-Dolphins

Posted by ESPN.com's Tim Graham

MIAMI -- The game is merely at the halfway point, but the Miami Dolphins look like world beaters -- or at least for the first 29:58 of the game.

The Dolphins lead the undefeated New Orleans Saints 24-10 at halftime, but it shouldn't be that close.

The Dolphins' defense not only has handled the high-powered and undefeated Saints, but the Dolphins have dominated so far in Land Shark Stadium.

Saints quarterback Drew Brees is having an awful day. He has thrown two interceptions, fumbled once (one of his linemen recovered) and came dangerously close to getting tackled for a safety. The Dolphins have sacked him three times.

Miami's defense has been on New Orleans tighter than a second coat of paint.

For the first 29:58 of the first half, the Saints' only points were set up by an 87-yard Courtney Roby kickoff return.

But a questionable decision by Dolphins coach Tony Sparano gave the Saints a touchdown instead of the field goal coach Sean Payton was willing to settle for.

A video replay took away a Marques Colston touchdown with five seconds left in the first half. The ball was spotted on the half-yard line, and with the Saints out of timeouts, the clock was going to run when the official set the ball.

The Saints had their field-goal unit on for what would have been an extra point. But Sparano called a timeout. That allowed Payton to send his offense back out, and Brees plunged in for a touchdown. The drive began on a Davone Bess fumble in Saints territory.

The Wildcat offense hasn't been as prolific as in previous games, but Dolphins running back Ricky Williams has had a big day. He has two touchdowns, the second on a career-long 68-yard run.
