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 Juan 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”. More to the point, both were hired specifically to bring outside elements to the offense -Helfrich the RPO game and Hiestand the power running. Neither worked out.
For Nagy, the best thing to do was to get back to the offense, to the basics. Whether the team intends on running version 1.0, 2.0 or jumping to 3.0 next season, they now have an offensive coordinator and line coach who have proven track records in accomplishing whatever version is required.
