In the 2006 season, Vaughn was named the SEC Special Teams Player of the Year and was a Lou Groza Award finalist.

Twice during the season he completed four field goals in a single game — in wins against Washington State and the eventual BCS Champion Florida Gators.

Vaughn's career total of 312 points made him the Auburn career-scoring leader ahead of Bo Jackson and Carnell Williams, and ranks tied for 12th in SEC history.

His 39 career field goals is a Tennessee State Record and ranks him tied for 4th in national high school football history.

He was released from the Titans after Tennessee's 3rd Pre-season game John Vaughn was signed by the Orlando Predators of the AFL in February 2008.
