Reminded me of an article I read a few years back:

"A year ago at the Hall of Fame reception in Canton, Ohio I found myself sitting between Bill Walsh and Don Shula. I posed this question: In a day when the Bears line up five-wide and Texas Tech passes 60 times a game, are there any fundamental innovations that have not been tried? Walsh supposed someone might try using trick formations for an entire game. Shula twinkled his eyes and said: 'Someday there will be a coach who doesn't punt.'"
