If the North Carolina football team’s head coach, Larry Fedora, coached your intramural flag football team, would you automatically win the championship?
Your team isn’t starting from scratch. You’ve got plenty of talent, but not much in the way of experience.
Fedora would install plays and provide structure to your offense. He would know how to get the ball to your best athlete. His playbook and route combinations would open up holes in the other team’s defense.
He’d simplify the playbook for your quarterback and tailor the offense around throws he could make. Some fun trick plays would cover up some of the deficiencies in your offense.
