The Indianapolis Colts' defense gave Todd Blackledge all the time he needed today and he completed 16 passes for 246 yards to enable the Kansas City Chiefs to break a club-record, seven-game losing streak, 20-7.

In his previous start, Oct. 20, he had thrown a club-record six interceptions and fumbled once.

It had been a bad week for the Chiefs, who have conceded the season to youth. There were rumors that Coach John Mackovic would be fired, then defensive end Mike Bell was arrested on drug charges. But the team led at the half, 17-0, and was never threatened thereafter. They hadn't won since Sept. 29 and are 4-8. The Colts (3-9) have lost four straight.

Blackledge, a third-year pro who Mackovic says will start the team's last five games, outpassed Matt Kofler of the Colts, 190 yards to virtually zero, in the first half.

Kofler, making his first NFL start, completed one of eight passes for 12 yards in the first half, but lost 11 yards on a sack. Mike Pagel relieved him early in the second half and the team finished with 86 net passing yards.

The Chiefs used 8:35 of the first period on a 14-play, 77-yard drive that Blackledge ended successfully with a 22-yard pass to Stephone Paige.
