The Wisconsin Badgers have a storied walk-on tradition. Year after year, players walk on to the Badgers team and work their way into the starting lineup, and many go on to have successful NFL careers.

Currently, nine former Wisconsin football walk-ons are on 90-man NFL rosters heading into 2017 training camps, and those nine players combine to average $33,353,740 per year in salary.

The group is led by a few high-profile players — as you'll see below — but the fact that nine former walk-ons from Wisconsin's program alone are currently on NFL rosters is a testament to the coaching staff at Wisconsin and their ability to mold players.

For anyone interested in learning more about the rich history of the walk-on tradition at Wisconsin, "Walk on This Way" by Joel Nellis and Jake Kocorowski is a must-read.

Maragos is a story of constantly working his way up the ladder. He started his college career as a wide receiver at Western Michigan, but transferred and walked-on at Wisconsin. During his transfer season he switched positions, and eventually worked his way into the starting lineup at safety.
