Kevin O'Connell just completed the most successful debut season in Vikings coaching history, guiding the 2022 squad to a 13-4 season against all odds.
His success stands in stark contrast to the least successful debut season in Vikings coaching history, when Les Steckel's 1984 Vikings went 3-13.
Norm Van Brocklin's expansion Vikings went 3-11 in 1961 and quite possibly would have gone 3-13 in two more games. Leslie Frazier's 2011 squad also went 3-13, but he had a six-game warmup in 2010 as interim coach and went 3-3 in those games.
Any perceived ties go to Steckel, whose lone season as a drill sergeant-style coach still lives in infamy.
