ProFootballTalk.com conducted a division by division vote then pitted the divisions against each other by conference.
In the end the Lions and Oakland Raiders were the only two teams left on the board with the Lions still attracting more interest for the show from PFT readers.
Unfortunately the Lions and other intriguing teams around the league like the Denver Broncos and the Tampa Bay Buccaneers don’t want to have anything to do with the TV series. Hard Knocks may be stuck with boring teams like Seattle and Buffalo.
