Tom Ramsey of UCLA, who led the nation's major college quarterbacks in passing efficiency last season, signed a four-year contract today with the Los Angeles Express of the new United States Football League.

No other terms of the contract were given at the press conference called to announce the signing of Ramsey.

"Today's signing of Tom Ramsey should give the Los Angeles community a clear indication of the L.A. Express' strong commitment to build a first-class professional football team," said Alan Harmon, the club's president and co-owner.

Ramsey, named a second-team all-America this season, was the most valuable player in UCLA's Rose Bowl victory over Michigan last month.

UCLA's starting quarterback for most of the past three seasons, Ramsey led the Bruins to a 10-1-1 record last season, including the 24-14 victory in the Rose Bowl.

Ramsey completed 209 of 366 passes for 2,986 yards last season and was intercepted only 10 times.

Andy Johnson, an eight-year veteran of the NFL's New England Patriots, has jumped leagues by signing with the Boston Breakers of the USFL.

Johnson, a free agent who wasn't offered a contract by the Patriots, ended his career with New England as the team's sixth all-time career rusher and ninth all-time receiver.
