Havig was chosen in the eighth round (189th overall) of the
1971 NFL draft by the
Atlanta Falcons. He did not make the team's final roster that year but stayed on their
taxi squad. He was named the Falcons' full-time starter in 1972 before even having seen any playing time. He ended up starting all 14 games that year and helped Atlanta finish with a record of 7–7, being named to the NFL's All-Rookie team and being chosen the team's rookie of the year. He then appeared in 14 games, 13 starts, in the 1973 season, repeated those totals in the 1974 season, and started all 13 games in which he appeared for the Falcons in 1975. He played all 14 games for the Oilers that year, none as a starter. The following month, he was signed by the
Green Bay Packers. He appeared in seven games for the team that year, between six and seven as a starter. Havig finished his eight-season NFL career with 76 games played, 58 or 59 as a starter. ==Later life==
