Matt Cavanaugh passed for one touchdown and ran for a second and halfback Andy Johnson threw a 66-yard scoring pass to Stanley Morgan as the New England Patriots won their first game of the season by defeating the Kansas City Chiefs, 33-17, today.

New England (1-4) got its first four interceptions of the year against Kansas City, two of them setting up touchdowns. Rookie Tony Collins scored on a 13-yard run for the Patriots and John Smith kicked two field goals, including a personal best 50-yarder in the third quarter.

Kansas City (3-2) scored on runs of one yard by fullback James Hadnot and 18 yards by rookie Joe Delaney. Nick Lowery kicked a 35-yard field goal for the Chiefs but failed on a 40-yarder, his first miss of the season under 50 yards.

"We didn't do anything different than the last few weeks, but we made fewer mistakes and got a couple of breaks," said Cavanaugh, who has replaced Steve Grogan as the Patriots' No. 1 quarterback.

The Patriots had 12 passes intercepted and lost four fumbles in their first four games, and were off to their worst start since 1975. They had two interceptions and no fumbles today. New England outgained the Chiefs, 451 yards to 327.
