In his day, Lawewllen was known as an excellent punter and back for the first three world champion Green Bay Packers teams, who won championships from 1929 to 1931 as the first dynasty of the NFL.

Because games in the early era of professional football were such so low scoring, punters were considered the most valuable players on teams due to their ability to control field position.

[6] As General Manager of the Packers, Lewellen had the assistance of talent scount Jack Vainisi (hired in 1950) in finding players to select.

[10] Together, they helped the team draft many notable stars that would eventually help coach Vince Lombardi win the franchise five NFL Titles, such as Bart Starr, Paul Hornung, Ray Nitschke, Forrest Gregg, Jim Taylor, Jerry Kramer, Ron Kramer, and Max McGee.

[11] Completing a law degree from University of Nebraska during his professional football career,[5] he ran successfully for Brown County (WI) District Attorney in 1928 against Packer teammate LaVern Dilweg and was re-elected in 1930.
