Johnson was selected by the Dallas Cowboys in the 3rd round (87th overall) of the 1976 NFL Draft.
In 1978, he tied an NFL record with the most punt returns (9) in a game, while playing against the Buffalo Bills.
He set a franchise record with 45 punt returns for 489 yards.
He also returned 28 kickoffs for 693 yards (24.8-yard avg.).

In 1977, he alternated with Golden Richards, recording 12 receptions for 135 yards (11.3-yard average) and one touchdown.
He also returned a club record 50 punts and led the team with 22 kickoff returns.
At the end of the year in Super Bowl XII against the Denver Broncos, he had his most notable career highlight, a 45 yard diving touchdown reception from Roger Staubach, which is considered to be a "Super Bowl Classic".
In the Dallas Morning News newspaper, after Super Bowl XII, on Monday, January 16, 1978, the front page photo was titled "Outfielder Butch", referring to his diving touchdown grab in the end zone, despite a broken thumb he suffered earlier in the game.

In 1978, although he couldn't earn a starting role over Tony Hill, he became the leading punt returner in franchise history while breaking again his single-season record with 51 punt returns and also placed second on the Cowboys all-time kickoff return list.
He had another touchdown reception in Super Bowl XIII which the Cowboys lost to the Pittsburgh Steelers, making him the second player in NFL history to score touchdowns in back-to-back Super Bowls.

In 1979, he fractured his right little finger in the preseason finale against the Steelers and was forced to miss the first 5 games.
With both Hill and Drew Pearson having 1,000-yard seasons, his opportunities were limited.
He started in the 15th game against the Philadelphia Eagles in place of an injured Pearson, and caught a deflected 17-yard pass for the decisive touchdown in the playoff-clinching victory.
He also stopped returning punts and kickoffs.

In 1981, he started the first 6 games in place of an injured Hill, finishing the season with 25 receptions for 552 yards and 5 receiving touchdowns (tied for the team lead).
He also developed a touchdown celebration known as the "California Quake", where he would simulate pulling guns out of holsters and proceed to shoot them and shake.
It became one of the most famous individual celebrations in league history, and one of the reasons the NFL banned rehearsed end-zone touchdown celebrations.

In 1983, he had his best year with 41 receptions for 561 yards, but he had grown tired of his third receiver status and requested a trade.
On April 12, 1984, even though Pearson had suffered a career-ending injury, the Cowboys granted his wishes and traded him to the Houston Oilers in exchange for wide receiver Mike Renfro, plus the right to swap second-round picks in the 1984 NFL Draft and the Oilers' fifth-rounder in the 1985 NFL Draft.
A year later, the Cowboys used that fifth round pick to select running back Herschel Walker.

For a long time he was considered one of the best-backup wide receivers in the NFL, but during his 8 seasons with the Cowboys he could never earn a starter position.
As the third receiver during that time, he was primarily known for his acrobatic and clutch receptions.
Besides leaving as the second leading punt returner in franchise history, he also was one of two players in club history to rank in the top ten career list in both kickoff and punt return average yards.
