One day after firing four assistants — including offensive coordinator Mark Helfrich and OL coach Harry Hiestand — Matt Nagy began assembling his 2020 coaching staff with the hiring of new OL coach Juan Castillo, NFL Media's Tom Pelissero reported Wednesday.
Castillo, 60, brings more than two decades of NFL assistant coaching experience to Chicago, where he'll reunite with Nagy after they teamed on the Eagles staff under Andy Reid from 2008-12. Castillo preceded Nagy — and Reid — in Philadelphia, beginning with the Eagles as an offensive assistant in 1995, with a year stint as tight ends coach and two seasons as defensive coordinator flanking his 12-year run overseeing the Eagles offensive line.
