Pat McAfee recounts Peyton Manning's maniacal film study

The Arizona Cardinals have ordered quarterback Kyler Murray to do homework as part of his lucrative new contract.

There are plenty of questions about how that addendum can be enforced, but it prompts questions about how much NFL quarterbacks should prepare.

Pat McAfee discussed how much film Indianapolis Colts legend Peyton Manning watched leading up to games.

Away we go:

"He dove into it. 'Gotta watch every game the other team's played; every snap they made; every practice clip from your week of practice; every game that your guys have played against a similar defense that they're playing; every single third-down situation broke up in there; every red zone; every first down.'

"I think he went through it all ‒ I think I like, prodded him a little bit ‒ and he was like, '20 hours of film a week?'"

McAfee said Manning's film study would run into Saturday, or perhaps the morning of a game.

"'How can I get more information? The more information I have, the better equipped I'll be to beat that defense.'"

And the Cardinals are trying to get Murray to commit to four hours a week.
