[7] Dowler was a two-time Pro Bowler in 1965 and 1967, and a key contributor on the Packers dynasty in the 1960s, assisting the team to five NFL championship wins and victories in Super Bowls I and II.

[8][9] A late hit by Dallas Cowboys defensive back Mike Gaechter in the end zone following a third quarter touchdown catch resulted in a shoulder injury in the 1966 NFL Championship Game.

Dowler aggravated the shoulder early in the first quarter of the first Super Bowl two weeks later, allowing seldom-used Max McGee to be a significant contributor in the game with two touchdown catches.

Dowler made a big impact the following year in Super Bowl II with a 62-yard touchdown reception from quarterback Bart Starr in the first half.

Notable positions that Dowler held included the passing game coordinator role for the Philadelphia Eagles from 1973 to 1975 and, his final stop, a scout for the Atlanta Falcons.
