"It was there."

Santana Moss was open down the left sideline and he had a step on cornerback Dewayne Washington. Mark Brunell's fourth-down pass was on target.

At the last second, safety Sammy Knight came over and knocked a potential game-tying touchdown pass away.

The Chiefs took over possession with eight seconds remaining and won the game, 28-21, at Arrowhead Stadium on Sunday.

"It was there," Moss said again. "You have to give it to the safety. It was a Cover 2. The safety played his half and he got over there and tipped the ball. This game is played on inches. If he had missed it, who knows what would have happened?"

Moss continues to develop into one of the league's elite wide receivers. He turned in a career day against Kansas City, with 10 catches for 173 yards and two touchdowns.

He caught the game's first touchdown in the second quarter on a 4-yard pass from Brunell. On the play, Moss ran a crossing pattern as Brunell rolled left and caught the pass on the run.

In the third quarter, Moss scored again. He caught a swing pass from Brunell and quickly turned up-field. He weaved his way through two defenders and followed a block by Chris Samuels.

Beyond Samuels, there was nothing but open field ahead.

Moss turned on the burners and out-raced everyone to the end zone. Coming across the field, Knight had the last chance to tackle him, but he was unable to trip him up.

"I thought it was one of the prettiest plays I've ever seen," head coach Joe Gibbs said. "We found a lane there and it went for big yardage. Santana is a playmaker, that's for sure. He had a ton of yards for us. That's the encouraging thing. He makes plays."

In the fourth quarter, the Chiefs' defense began to put more of an emphasis on stopping Moss and the fifth-year receiver was held without a catch.

"Their defense made some adjustments," Moss said. "You have to give them some credit. At the same time, we're all in this together. Maybe if I get the attention, someone else can get open. It's going to be like that sometimes."

Moss welcomes the status of No. 1 receiver. It's been something he has strived for since he entered the NFL as a first-round draft pick of the New York Jets in 2001.

So far this season, Moss has 33 catches for 631 yards, a 19.1 yards-per-catch average, and four touchdowns. The yardage total leads the NFL through six weeks of the season.

"I'm going to put that pressure of being No. 1 on my back," Moss said. "But I'm not going to be a guy who always wants the ball because you never know what kind of look you're going to get from the defense. Sometimes another receiver might be open and be the better option."

Moss said the offense needs to play all four quarters with the intensity the team had in the fourth quarter against the Chiefs.

"We have to have that same attitude when it's not at crunch time," he sad. "That's when we can really take the game over and not have to go through that at the end. The more we play with each other, the more we'll do that."
