"We are excited about the addition of these two fine football coaches to our staff," Callahan said. "Both coaches add tremendous value and experience to our coaching staff and will continue an ongoing Nebraska tradition of outstanding coaches in our graduate assistant positions."
Heckendorf was elevated to a graduate assistant position after he spent the 2005 season serving as Nebraska's offensive video intern.
Prior to joining the Nebraska football office, Heckendorf had a standout collegiate career as a quarterback at St. Cloud State University from 2000 to 2003. A native of Mosinee, Wis., Heckendorf was one of three finalists for the 2003 Harlon Hill Trophy, given annually to the top player in the Division II ranks, and was a consensus All-America pick in both 2002 and 2003.
Heckendorf owns numerous St. Cloud school records, including career school records for passing yards (9,695), pass completions (761), completion percentage (58.2), touchdown passes (101) and total offensive yards (9,997). As a senior, Heckendorf led the North Central Conference and ranked 10th nationally in total offense at 289.9 yards per game, while throwing for 30 touchdowns.
Heckendorf was also accomplished in the classroom during his time at St. Cloud State. Heckendorf was a two-time College Division Academic All-America selection, was a 2003 National Football Foundation/College Hall of Fame Scholar-Athlete and was the Division II Men's Winner of the 2003 Woody Hayes Award.
Osterhout joins the Nebraska staff after spending the past five seasons on the coaching staff at Division I-AA Sacramento State. Osterhout served as the Hornets' defensive line coach from 2002 to 2005, after coaching the tight ends in 2001. In addition to his on-field coaching duties, Osterhout served as Sacramento State's camp director the past two years.
In Osterhout's first year as defensive line coach, the Hornets allowed 90 fewer rushing yards per game than the previous season and registered 12 sacks more than the previous year. In 2005, Sacramento State recorded 71 tackles for loss, spearheaded by a strong defensive front.
Osterhout enjoyed a standout playing career at Sacramento State from 1995 to 1999. A four-year starter on the offensive line, Osterhout was a two-time All-Big Sky Conference selection and earned first-team All-America honors as a senior. He also served as a team captain for the Hornets and was voted the team's most inspirational player as a senior. Osterhout signed a free agent contract with the Washington Redskins following his graduation from Sacramento State.
