Hard Knocks (2001)

It's been ten years since HBO Sports and NFL Films debuted 'Hard Knocks: Training Camp with the Baltimore Ravens.' In the decade since, 'Hard Knocks' has gone inside the locker room of five different teams, twice with the Dallas Cowboys. Every season has provided unprecedented inside access to players and coaches from the NFL and plenty of memorable moments-from Emmitt Smith preparing for his final season, to Chad Ochocinco inventing catchphrases seemingly on the fly, and Rex Ryan's famous "Let's go get a goddamn snack" speech.
