If you have any doubt that the NFL coaching ranks is an old boys network, consider Juan Castillo, a washout in Philly with the Eagles and the Bills.
Castillo will replace Harry Hiestand as the Bears’ offensive line coach, Tom Pelissero of the NFL reports.
Castillo did not coach in 2019 following his dismissal from the Bills after the 2018 season. He has spent 24 seasons as an NFL assistant, including 18 with the Birds.
Castillo worked with Matt Nagy for five seasons in Philly.
Castillo has a reputation as one of the best offensive line coaches in football. He was the Eagles’ offensive line coach for 13 seasons, the Ravens’ offensive line coach for three seasons and the Bills’ offensive line coach for two seasons.
The Bears also dismissed offensive coordinator Mark Helfrich, tight ends coach Kevin Gilbride Jr. and assistant special teams coach Brock Olivo on Tuesday.
