Joe Barry

Joe Barry loves a good cup of coffee. But he doesn't stop there -- he'll keep going all day long, drinking roughly 10 cups every day.

If you think that's unhealthy, Washington's defensive coordinator has a message for you: You're wrong. As he explains to ESPN, he's very confident that his habit is perfectly safe.

"Caffeine is not bad for you," Barry says. "It gets a bad rap, but as long as you're drinking water with it. ... But I don't get headaches from it.

"I probably lie a little bit when I go to the doctor. I probably say, 'Yeah, I have three cups a day.' But as long as you hydrate with it, coffee's not that bad for you."

Barry says he never drank coffee until he became a graduate assistant at USC in the 1990s. Ever since, coffee has been an occupational necessity for the defensive coordinator.

"I really can't function before I have a cup of coffee," he tells ESPN. "My alarm goes off and regardless what time I get up, the first thing I do is walk over and have a cup of coffee."

Not only that, but in between his cups of coffee he isn't opposed to taking down a Red Bull or two. And where some would recommend cutting down or quitting cold turkey, Barry isn't ready to listen.

"I would not want to try to go through a day without it, saying, 'Hey, you know what, tomorrow I'm not going to drink coffee and see how it is.' I’m not going to do that."

You see? Joe Barry is not addicted to coffee. He can quit coffee whenever he wants.

The thing is, he doesn't want to quit. And no one's going to change his mind.
