Ray Malavasi, who coached the Los Angeles Rams to the Super Bowl in 1980 but had losing records the last two seasons, and Marv Levy, praised by an official of the Kansas City Chiefs as a "very good fundamental coach," were fired by their National Football League teams yesterday.

Rams owner Georgia Frontiere said in a prepared statement: "We are indebted to Ray for some fine seasons of football. He helped us into the playoffs three times, won two division championships and coached our first Super Bowl team. Unfortunately, the results of the past two seasons have fallen short of our goal to give our fans a winning team.

"I have a strong personal feeling of friendship for Ray. He is a fine and loyal person. However, I feel, for the sake of our fans, it is time to make a change."

The Rams were 2-7 this season after going 6-10 in 1981. Malavasi had guided them to a 12-4 record after becoming coach in 1978, then 9-7 in 1979 and 11-5 in 1980.

"There are more coaches who fail than succeed," said Lamar Hunt, owner of the Chiefs. "We made an evaluation. We asked ourselves if we could reasonably hope to get into the playoffs next year under the present coaching situation. Our evaluation was, no, we really don't believe we'll be in the playoffs."

Team President Jack Steadman said the more than 66,000 empty seats Sunday as the Chiefs upset the Jets were a factor.

"We're in the sports entertainment business. The team is the product," Steadman said. "That's where you've got to get it done."

The Chiefs were 3-6 this season, the 11th straight they had not gained the playoffs.

In Houston, the Oilers said they will keep Ed Biles as coach next season despite a 1-8 record, their poorest since 1973. Biles' two-year contract expires after next season.

The announcement that Biles will be retained followed a lengthy meeting between Biles, team owner K.S. (Bud) Adams and General Manager Ladd Herzeg.

Adams said many factors entered into his decision to retain Biles, including the difficult situation in which Adams placed Biles--hiring him immediately after the firing of popular coach Bum Phillips Dec. 31, 1980.

Place-kicker Mark Moseley was the only member of the Washington Redskins selected on the first team of The Associated Press All-Pro team announced yesterday.

The San Diego Chargers, in contrast, placed quarterback Dan Fouts, wide receiver Wes Chandler and tight end Kellen Winslow the first team.

Moseley was honored Monday by the AP as the National Football League's most valuable player.

Fouts has completed 204 of 330 passes for 17 touchdowns and 2,889 yards. This is his fourth consecutive season as the yardage leader, adding to a league record he already held.

The other starting wide receiver is Dwight Clark of the San Francisco 49ers, who leads the league with 60 catches for 913 yards and five touchdowns. Winslow has 54 catches for 721 yards and six touchdowns, Chandler 49 catches for a league-high 1,032 yards and nine touchdowns.

The running backs are Freeman McNeil of the New York Jets, the league rushing champion with 786 yards on 151 carries and six touchdowns, and Marcus Allen of the Los Angeles Raiders, the only rookie on the team. Allen has gained 697 yards on 160 carries and has a league-high 11 rushing touchdowns.
