Joe Kapp, the quarterback with an unorthodox style who took the Vikings to their first Super Bowl in 1969, has died at age 85.
His son, J.J. Kapp, confirmed the death to the San Francisco Chronicle, writing in an email that Kapp died after a "15-year battle with dementia."
Kapp was a quarterback in the Canadian Football League before joining the Vikings in 1967. He was known for a hard-nosed running style and throwing passes that were rarely pretty but often wobbled their way into completions.
Kapp played for only three seasons in Minnesota and one more with the Patriots before leaving pro football in the aftermath of a contract dispute.
