That’s a very limited view of what a coach is/does. He’s an amazing recruiter, leader, and culture builder.
He may not be an x’s & o’s savant but I’d argue that is less imperative in the current version of the game than it was in 70’s-00s.
Get your guys, get them gelling, establish some actions and let them go. More like soccer than football.
Add in the portal, ego management etc. there’s not much room for militant x’s & o’s where a coach is allowed freedom to do what he wants as long as he knows the game. From fans, administration and players alike.
TJ is objectively a great coach.
