Hard Knocks was created in 2001 and rather than following a team that had been struggling, the first season focused on the reigning champions, the Baltimore Ravens. The next year was the Dallas Cowboys and then after a five-year hiatus, Hard Knocks returned to camp with the Kansas City Chiefs, followed by a repeat appearance of the Cowboys. So Dallas was the first team to repeat Hard Knocks.
And unless you’re a girl scout just dying to push three packs of samoas and a thin mints to this two-story in a cul-de-sac, most try to avoid repeating Hard Knocks.
