Michigan hires analyst with ties to Andy Reid, Jim and John Harbaugh

Michigan has added an analyst to its staff with decades of experience in the NFL and NCAA. Michigan has hired Juan Castillo, who served as UCLA’s offensive line coach in 2024.

Castillo, 65, was with the Philadelphia Eagles from 1995-2012, where Andy Reid was head coach for the majority of those seasons. Castillo served as offensive line coach during a stretch of the Reid era when the Eagles made the NFC Championship Game five times. Baltimore Ravens head coach John Harbaugh was also on the Eagles staff from 1998-2007, Castillo’s relationship with Harbaugh led to him joining the Ravens staff from 2013-16, first as run game coordinator (2013) and then as offensive line coach (2014-16) before heading to the Buffalo Bills in 2017-18 as offensive line coach and run game coordinator.

John Harbaugh isn’t the only Harbaugh Castillo has worked for. Castillo was also on former Michigan head coach Jim Harbaugh’s staff at Michigan in 2019 as an offensive analyst. After Castillo’s lone season at Michigan he went on to be the Chicago Bears offensive line coach in 2020 and 2021, then the Washington Commanders in 2022 and 2023 as offensive line coach and run game coordinator, with his most current stop being offensive line coach at UCLA in 2024.

While Castillo has coached a variety of positions in his career, his bread and butter is clearly coaching the offensive line. Castillo, 65, will likely be working closely with Michigan offensive line coach Grant Newsome. In June of 2024, the NCAA made a big rule change, lifting restrictions on football analysts and allowing any staff member to provide “technical and tactical instruction” to student-athletes. In short, Castillo will be able to provide on-field instruction and coaching at practices. Castillo’s presence should be beneficial to Michigan’s offensive line and to Grant Newsome, who’s considered an ascending coach at 27 years old.
