Preparing to take the field for an upcoming football season takes hours and hours of dedicated work, film study and preparation.
And then fall practice starts.
The amount of time dedicated to this game is enormous, with good reason.
As the immortal Vince Lombardi told us: "Practice does not make perfect. Only perfect practice makes perfect."
Unless, of course, you prepare for those untold hours only to have a monkey wrench thrown in the works at the last instant: an injury, suspension or other loss of player could leave your squad reeling from having to cover unexpected gaps.
The teams on this list could all use more time for preparation, or just need more time to rest on their laurels before the season kicks off.
