Want to be a defensive coordinator? Read this
Want insight into a defensive coordinator's mind? You should read this article about how Kevin Steele (Clemson's defensive coordinator) prepares for each game by Travis Sawchik of the Post and Courier.
Excellent article initially focusing on opponents' trends and probabilities; but then dives much deeper into game day decisions and analysis of opposing play callers.
"Steele typically trusts the numbers...[but] I never battle a gut feeling."
Steele also gives good insight into why he chooses to be on the sideline during games.
Really a good read. Full article available at this link.
