Jordy Nelson is probably the best walk-on to ever play at Kansas State. The Riley County, Kansas native was a walk-on at Kansas State in 2005 and was a starter by his final year in 2007. He was drafted by the Green Packers in the second round with the 36th pick.
In the NFL, Nelson immediately became a star and a favorite target for Packers quarterback Aaron Rodgers. Nelson did win a Super Bowl with the Packers in 2011 and won Comeback Player of the Year in 2016. Nelson played his last season with the Oakland Raiders but signed a one-day contract with the Packers to retire with the team that drafted him.
Nelson had 8,587 receiving yards and 72 total touchdowns in his 10-year NFL career.
