Dallas Cowboys to be featured on HBO's 'Hard Knocks' for 2021 training camp

"Hard Knocks" never had such an easy decision. The long-running series documenting an NFL team's training camp, produced by NFL Films and HBO, will feature – who else? – the Dallas Cowboys this summer, NFL Films announced Friday. This will mark the 16th iteration of "Hard Knocks" with the Cowboys making their third appearance – most in the series' history – not that there was really any other choice.
