It also involves power blocking, one on one, NOT freakin' zone blocking. You know, the way it was the previous 2 years.
Precisely correct. The HC hires an OC who reflects his approach. If he doesn't like something about his "system," he tells him to change it. If the OC doesn't change it, he replaces him. That there have been no changes and Dennison still has a job says that McD is comfortable with this offense. I for one am concerned about putting a rookie franchise QB's future in the hands of these 2 guys. Shades of Jeff Fisher and Goff.
