If you love football, you'll enjoy watching the 5 best football documentaries. Football is as much a part of Americana as apple pie and the fourth of July, and each of these football documentaries provides a unique look at professional and college football. From Lombardi to Rex Ryan, football fans are sure to love every hard-hitting, sports highlight packed minute of entertainment in these documentaries.

  1. "Hard Knocks" - An annual documentary series produced by HBO and NFL Films, "Hard Knocks" follows the training camp of a different team each year in the weeks leading up to the NFL. People involved with all areas of an NFL team are profiled and interviewed, including management, coaches, trainers, franchise stars, and practice squad players trying to make the team. This is the best football documentary because of the unprecedented behind-the-scenes look it gives NFL fans.

  2. "The U" - Released as part of ESPN's award-winning documentary series "30 for 30", "The U" looks at the rise of the University of Miami's football program in the 80s and early 90s. Miami rose to national prominence by recruiting almost exclusively from Miami's lower income neighborhoods, one of the biggest hotbeds for elite talent. Along the way, players made as many headlines off the field as on it. Whether you find the actions of "The U" appalling or hilarious, you're sure to be on the edge of your seat the entire time.

  3. "Lombardi" - Another football documentary coming from HBO and NFL films, "Lombardi" is a profile of the most iconic coach in the history of the game. Vince Lombardi is legendary for his motivational tactics and on-field success, but "Lombardi" looks beyond the wins and losses into the man he really was. Family members, former players, and former opponents all chime in to give their opinions on the grandfather of modern football.

  4. "Inside Academy Football: Air Force" - The "Inside Academy" series produced by CBS College Sports Network looks at the lives of college football players at each of the United States' service academies, and this is the best of the three. Watch senior tailback Jared Tew and junior defensive back Jon Davis as they try to balance the rigors of the Air Force Academy with the lifestyle of a college athlete.

  5. "NFL: A Tradition of Defense: The Chicago Bears" - Although this focuses on the Chicago Bears, you don't need to be a fan of the team to enjoy this football documentary. Chicago has a proud history of star defensive players, including Dick Butkus, Mike Singletary, and Brian Urlacher. This DVD is one of the best football documentaries because of its focus on what was probably the most infamous (and possibly best) football team ever ... the 1985 Superbowl winning Chicago Bears.
