When the 2007 season came around, Stubblefield hung up his cleats and returned to his home state of Washington, where he was named the wide receivers coach for Central Washington University. The following season, he took the same position with Eastern Michigan, while also working towards his master's degree. For the 2009 and 2010 seasons, he was asked by former Purdue Defense Coordinator Brock Spack to take the wide receivers coaching position at Illinois State. For the Redbirds, Stubblefield coached Eyad Salem, who broke the school's single-season receptions record (92 catches) and twice tied the single-game receptions record with back-to-back 14-catch efforts. Salem was an All-MVFC first-team selection. The next year, he took a job with Central Michigan as their wide receivers coach. After stops at New Mexico and Wake Forest, Stubblefield was hired with a two-year contract at Utah. Utah recorded 9-4, and 10-3 seasons and attended the Las Vegas Bowl both years. Stubblefield's contract was not extended after his original deal and he moved on to coach with the Toronto Argonauts of the CFL for one season before joining Troy Calhoun's staff at the United States Air Force Academy in February 2017.
