If you do not have HBO or if just simply missed the season premier of Hard Knocks, it can currently be viewed in it\’s entirety on the website of movie channel, according to Pro Football Talk.
The NFL documentary of course features the Cincinnati Bengals and it includes quite a bit of former Pittsburgh Steelers linebacker James Harrison, who figures to be a recurring main character throughout the season.
I\’m not sure how long it will be available, so you might want to watch it as soon as you can.
