Tony Gonzalez won't lie. Of course he's thinking about starting for the AFC in the Pro Bowl.

"If I said that wasn't a dream of mine, I'd be telling you a real whopper," said Kansas City's hard-working tight end, who caught six passes for 93 yards and two touchdowns in a 35-19 victory over Pittsburgh today that gave the Chiefs the lead in the AFC West.

It was the second game in a row Gonzalez has caught two touchdown passes for the Chiefs (9-5), who won their fourth a row and moved a half-game ahead of Seattle. Gonzalez has scored in each of the four victories while setting a club record for his position with 10 touchdowns on the year.

The Chiefs, who play at Seattle next week, took the lead for good in the second quarter on Donnie Edwards's 28-yard interception return. The Steelers (5-9) lost their sixth straight game, the team's longest skid since 1988.

"We knew every time they needed a big play they would go to [Gonzalez]," Pittsburgh defensive end Kevin Henry said. "If you shut him down, you have a chance."

Gonzalez, the first dominant player at any offensive skill position the Chiefs have developed in more than 10 years, even threw the final key block on an 82-yard touchdown run by Derrick Alexander in the third quarter.

After slowing because he thought Alexander had been tackled, Gonzalez regrouped and leveled Pro Bowl linebacker Levon Kirkland as Alexander completed the Chiefs' longest scoring run since 1981.

The Steelers scored 10 points on their first two possessions and added a field goal at the end of the half, but then were shut out until Mike Tomczak's 11-yard touchdown pass to Bobby Shaw with 34 seconds left.

Former Steeler Bam Morris got the Chiefs' last touchdown on a 10-yard run with 1 minute 56 seconds left.

Gonzalez caught scoring passes of 15 and two yards from Elvis Grbac. He also had a 23-yard reception to set up his second touchdown catch, which put the Chiefs up 21-10 late in the first half.

Alexander, a starting wide receiver, put the game out of reach with his tackle-breaking 82-yard score on an end-around. Five Steelers appeared to get a hand on him, then Gonzalez provided the last key block.
