Yes, I think Leslie Frazier, Ron Rivera, and Sean McDermott are all on a branch from the Jim Johnson tree.
Jim Johnson was an innovative, attacking the QB coordinator.
And all of these guys started out that way.
But when these guys got their own chances:
Leslie Frazier favored a Tampa 2, bend but don't break simple scheme. He also liked to punt.
Ron Rivera handed his defense over to Sean but is known by fans as a VERY conservative head coach who punts the ball a lot.
Sean is the next one to get a chance. We shall see but his scheme in Carolina has become more similar to Frazier's Tampa 2 than what he originally was learning with Jim Johnson. He also selected Frazier to run his D, an ominous sign.
