Randy Robbins blocked two punts to set up a pair of scores, and Gerald Willhite ran for two short-yardage touchdowns to lead the Denver Broncos over the Kansas City Chiefs, 30-10, in an NFL game today.

The Chiefs (3-5), who lost their fourth straight, failed to pick up a first down on their first four possessions, and each punt by Jim Arnold led to a score as Denver built a 24-0 lead.

Willhite, who gained 55 yards on 13 carries before he suffered a concussion late in the half, dived in from the one on the Broncos' first possession. Rich Karlis kicked a 24-yard field goal later in the quarter.

Gene Lang plowed in from the one for another Denver touchdown seven seconds into the second period. After Robbins' second block, Willhite slanted in from the three for a 24-0 lead.

"The blocked punts obviously were a key for us," Denver Coach Dan Reeves said. "Chan Gailey, our special teams coach, told me during the week he thought we could get to them. He saw something in the films and, of course, Robbins did a great job. He's a big back with speed and quickness, and it showed."

"I don't really know what happened," Arnold said. "My responsibility is to punt the ball. I can't be watching what happens in the line."

The Chiefs finally scored after a 75-yard drive that culminated in Ethan Horton's one-yard run. Then John Elway marched the Broncos (6-2) from their own 19 to the Kansas City five. Karlis kicked his second field goal of the game, a 23-yarder, as time ran out in the half, giving Denver a 27-7 cushion. Karlis added a 19-yard field goal early in the fourth quarter.

Nick Lowery kicked a 33-yard field goal for Kansas City in the third quarter after Bill Kenney and Stephone Paige hooked up on a 53-yard pass, the Chiefs' longest play this season.
