Perhaps the Chicago Bears offense failing to achieve the Version 2.0 Matt Nagy promised before the season was because he had too many people to teach.
Early in Nagy’s tenure, before the first training camp practice, he regularly brought up the fact that it wasn’t just the players who had to learn the offense, but the coaches. Now with Luis Castillo as his offensive line coach and (reportedly, by DBB) Pat Shurmur as the offensive coordinator, Nagy has filled his staff with some of this offense’s finest teachers.
Mark Helfrich and Harry Hiestand are probably very good coaches, but neither was well-versed in what’s commonly known as “The Andy Reid Philosophy”.
