Baylor coach Art Briles abandoned the playbook several years ago, and he and his assistants teach their players the fast-paced spread offense through countless repetitions in practice and by watching hours of film.
"When I was at Houston, the first thing everybody wanted was the playbook," said Briles, who coached the Cougars from 2003 to '07. "A guy's not going to read or study it. Kids play video games, so we show them the plays on video. Everything is on an iPad, and we label it and number them. A playbook is something we don't do.
"I'm a visual learner, and people learn differently. If you can see something, you remember it. If you read it and try to interpret it, it's a little different. We do a lot of repetition on the field so guys can learn it."
