According to Walter Football, ESPN analyst Jon Gruden is thinking about a return to the NFL coaching ranks.

The report implicates "sources around Gruden have shared" that the former Super Bowl head coach is looking into different assistant coaches and their availability next season.

Interestingly enough, former Eagles defensive coordinator Juan Castillo is on his short list, as is San Diego Chargers special teams coach Rich Bisaccia.

Castillo and Gruden were on the same staff in Philadelphia under Ray Rhodes and have remained close throughout the years. Castillo was entering his first season as an Eagles assistant working with the tight ends, while Gruden was the offensive coordinator.

Ever since Gruden was fired by Tampa in 2008, rumors have been swirling as to where his next coaching gig would be. Since his firing though Gruden has remained active in the league commentating for Monday Night Football. Gruden is also well versed in the college game spending time with Oregon Ducks head coach Chip Kelly. He's also served as an analyst for ESPN's coverage of the NFL Draft.

With a coach like Gruden in such high demand, Gruden has said his return to coaching will depend on the situation. He's no longer interested in coaching a small-market team, rather wants a big-market, highly talented team with strong ownership.

Hello Philadelphia.

With Andy Reid's likely exit after the season growing more and more likely, team owner Jeffrey Lurie will be looking to make a splash hire and avoid an unknown inexperienced head coach.

The report also mentions the Dallas Cowboys and New York Jets as possible landing spots if those coaches are fired.

If the arisen opportunities aren't to Gruden's liking, he is perfectly happy with his broadcasting gig and will continue to monitor the NFL coaching carrousel.
