Campbell started building this 4y ago, getting comfortable with the idea of 4 downs, not 3. Teams are now trying to emulate him, but their mindset is not the same. He has said repeatedly, "we are built for this". Same with 'trick plays'. I am convinced. They have go-to plays and if they miss, it does not infect them. They stay the course. Winning creates so much motivation to keep that faith in him and the riskiness some call recklessness.
O'Connell failed yesterday wrongly trying to match Campbell. His team is not built for it.
Go Lions!
EDIT ADD: And we have a great offense that makes 4th down tries less risky for us. He plays these odds.
