No, I'm not. Tom Brady was still coached by a defensive minded coach in New England when he won Superbowls there within the last decade. Do you think he ceased development?
Brady was developed into a franchise QB over 2 decades ago.
Again, you're completely out of context of the conversation which was naming when a QB was developed into a franchise QB by a defensive head coach in the last decade. Not when an already franchise QB won a superbowl who was developed by a defensive head coach.
