NFL Films is making a feature about Andy Reid’s NFL coaching tree. Reid and a bunch of his proteges were spotted being filmed together at the NFL’s owners meetings this week.

This is cool. The Andy Reid Coaching Tree at NFL Annual Meeting in AZ. An NFL Films feature for 2017 season. Can you name all the coaches? pic.twitter.com/TKQ76hIgUu — Dave Spadaro (@EaglesInsider) March 26, 2017

No real formal details are known about this feature yet, but it seems like it could be pretty cool. Reid’s coaching tree is very impressive.

Reid obviously never won the Super Bowl (as if I needed to remind you) with the Eagles, but he had a lot of success as Philadelphia’s head coach from 1999 to 2012. He’s done pretty well for himself with the Chiefs since being hired by Kansas City in 2013, too.

During Reid’s tenure as a head coach in the NFL, a total of nine of his assistants have gone on to become head coaches themselves. Can you name them all without looking?

Give up? OK, here you go.

Brad Childress, Minnesota Vikings (2006–2010)

John Harbaugh, Baltimore Ravens (2008–present)

Steve Spagnuolo, St. Louis Rams (2009–2011)

Leslie Frazier, Minnesota Vikings (2010–2013)

Ron Rivera, Carolina Panthers (2011–present)

Pat Shurmur, Cleveland Browns (2011–2012)

Todd Bowles, New York Jets (2015–present)

Doug Pederson, Philadelphia Eagles (2016–present)

Sean McDermott, Buffalo Bills (2017–present)

As you can see, five of Reid’s assistants are currently head coaches, including Doug Pederson. The ones who aren’t head coaches still hold prominent coaching jobs in the NFL. Childress holds the position of assistant head coach in Kansas City. Spagnuolo is the Giants’ defensive coordinator and Frazier has the same title with the Bills. Shurmur is the Vikings’ offensive coordinator.

Reid’s coaching tree could easily grow in the future. Chiefs special teams coordinator Dave Toub has drawn head coaching interviews in recent years. Eagles running back coach was interviewed for Philadelphia’s vacancy last year and some believe he could earn a head coaching job one day.

Even though Reid didn’t ultimately get the job done in Philly, he’s still one of the best coaches in the league. His extensive coaching tree is just another reminder of that fact.
