Zierlein grew up in Lenora, Kansas. After spending two years in the Marines from 1966 to 1968, including a tour of duty in Vietnam in 1967, he attended Fort Hays State College. He played defensive end for Fort Hays State in 1969 before graduating in 1971.
Zierlein embarked on his coaching career as a graduate assistant and linebackers coach at his alma mater in 1970. After two years coaching at Fort Hays State, he spent the following six seasons (1972–1977) as a high school assistant in Texas. In 1978, he returned to the college game at the University of Houston where he served as offensive line coach for nine seasons.
In 1987, he got his first professional experience as an assistant with the Washington Commandos of the Arena Football League. When the Commandos went on hiatus the next year, Zierlein took a job at Tulane where he worked the next three seasons before returning to the pro ranks with the New York/New Jersey Knights of the National Football League's development league, the World League of American Football. With the Knights he held the title of offensive coordinator under Mouse Davis as well as coaching the offensive line. When the Knights folded in 1992, Zierlein once more headed back to college, this time at LSU.
Zierlein spent two years at LSU, coaching the offensive line under head coach Curley Hallman. In 1995, he returned to Tulane, this time for what would be a two-year stint under Tommy Bowden. In 1997, he moved on to the University of Cincinnati as the running game coordinator and offensive line coach under Rick Minter.
In 2001, Zierlein gained his first NFL experience with the Cleveland Browns. He served for four seasons as the Browns' offensive line coach under the Butch Davis regime. Zierlein's current Pittsburgh Steelers colleague Bruce Arians served as the offensive coordinator for the first three of Zierlein's seasons at Cleveland. He returned from a one-year absence from football in 2006 as the assistant offensive line coach for the Buffalo Bills under Dick Jauron.
When Mike Tomlin was hired as the Steelers new head coach in 2007, he brought Zierlein to Pittsburgh to coach the offensive line. Tomlin and Zierlein had previously worked together in 1999–2000 with the Cincinnati Bearcats. Steelers assistant special teams coach Amos Jones was also a member of that Bearcats coaching staff. Zierlein was relieved of his duties with the Steelers on January 6, 2010.
Zierlein gained unwanted notoriety in 2007 when he mistakenly forwarded an e-mail to a large number of high-level NFL employees, including commissioner Roger Goodell. The e-mail, which Zierlein had received from Steelers pro personnel coordinator Doug Whaley, contained an inappropriate video. Zierlein apologized for the gaffe, but was not disciplined by the team or the league.
Zierlein and his wife, Marcia, have three children and several grandchildren. Their son Lance is a sports talk radio host at Houston's "Sports talk 790" and a writer for NFL.com. Their son Mike (Lance's brother) is the assistant football coach at Cypress Ridge High School in Houston, Texas.
