Former Oregon, Philadelphia Eagles and San Francisco 49ers coach Chip Kelly has long been a resource in the coaching community, one willing to exchange ideas in the offseason during visits with other coaching staffs. 

This week, he's popped up at Navy's spring practice where the Midshipmen are "just trying to soak in as much as we can," per coach Ken Niumatalolo. 

"Some of the things he did at Oregon revolutionized football," Niumatalolo said, via the Washington Post. "Everybody's doing no-huddle, one-word concepts. His offseason stuff, his up-tempo stuff, a lot of the things that he implemented, literally high school, college and pro guys are doing it. He's definitely a trendsetter."

Kelly's return to college football has been rumored nearly every offseason since he left Oregon in January 2013 to become coach of the Philadelphia Eagles. Now out of work and without a team for the first time, Kelly has time to refine the system that revolutionized parts of football at all levels. Maybe Navy's influence will be a dominant one when/if Kelly comes back to college football, leading an up-tempo triple-option attack all the way to the College Football Playoff.
