# Jim Leonhard

James Andrew Leonhard (born October 27, 1982) is an American professional football coach and former safety who is currently the defensive pass game coordinator and assistant head coach for the Denver Broncos of the National Football League (NFL).
Leonhard played college football at Wisconsin and professionally as safety for ten seasons in the NFL. Leonhard was signed by the Buffalo Bills as an undrafted free agent in 2005 after playing college football at the University of Wisconsin. He also played for the Baltimore Ravens, New York Jets, Denver Broncos, New Orleans Saints, and Cleveland Browns.

## Early life

Leonhard played high school football at Flambeau High School in Tony, Wisconsin, where he was the starting quarterback and strong safety. During his freshman year, 1997, the Flambeau Falcons won the Wisconsin state championship in football in division six over River Ridge high school. He was a team captain in his junior and senior seasons, the same seasons in which he was a first-team All-State performer. He was also named team MVP in his senior year.

## College career

Leonhard was a walk-on football player at the University of Wisconsin–Madison, having received no Division I-A scholarship offers out of high school. He was not awarded a scholarship until his senior year, despite the fact that he had been a regular starting safety before that season and had already been named All-Big Ten twice. Noted for his speed, leaping ability, and sure tackling, he totaled 21 interceptions (tied with Jamar Fletcher for the most in school history) and made 281 tackles. He held the Big Ten Conference career punt return yardage record with 1,347 yards until Michigan's Steve Breaston eclipsed his mark in 2006.

## Coaching
### Wisconsin

In his year off between retiring from the NFL and being named DB coach for the Badgers, Leonhard spent his time studying college film with then-Wisconsin Defensive Coordinator Dave Aranda and familiarizing himself with schemes that exist in college football that aren't prevalent in the NFL, such as the zone-read option offense. Prior to UW DB coach Daronte Jones leaving UW for an assistant coaching position with the Dolphins, Leonhard had been asking Paul Chryst about joining the Badgers staff.
In February 2017, Leonhard was named the new defensive coordinator of the Badgers, replacing Justin Wilcox, who became the new head coach of California. In late November 2017, Leonhard was named one of five finalists for the Broyles Award which recognized the top assistant coach in college football.
On October 2, 2022, Leonhard was named interim head coach of the Badgers following the firing of Paul Chryst.
After Wisconsin hired Luke Fickell as head coach in November 2022, Leonhard announced that he would be leaving Wisconsin at the end of the 2022 football season.
