in 1977. Siemon was the 10th overall selection of the
1972 NFL draft, taken by the
Vikings with a pick acquired from the
New England Patriots in the trade for
Joe Kapp, the Vikings' starting quarterback in
Super Bowl IV. Siemon played for the Vikings for 11 seasons, retiring after the strike-shortened
1982 campaign. During that time, he was the starting middle linebacker in four NFC championship games over the course of five years (
1973–
1977), winning three:
1973,
1974, and
1976, losing one:
1977, and three Super Bowls (
VIII,
IX,
XI), all losses. He was also a vital part of the Vikings'
1975 season of 12 wins and 2 losses, winning the NFC central division, third in the NFL in fewest points allowed (180 points, 12.9 points per game), but the team lost to the
Dallas Cowboys in the first round of the
playoffs. During the prime years, he teamed up with excellent outside linebackers, such as
Matt Blair,
Roy Winston, and
Wally Hilgenberg. For his speed, quickness, and savvy, he was chosen to play in four
Pro Bowls. ==Later years==
