There’s no doubt who the real star of the first episode of HBO’s Hard Knocks was when the NFL training camp documentary premiered for its tenth season this past Tuesday; it was none other than J.J. Watt. The Houston Texan’s DL and team leader was front and center throughout the show’s one hour airing. In one memorable scene, Watt showed his fervent dedication for staying at the top of his game by training long after camp had ended for the day. Check out this footage from last night’s premiere. Earlier in the episode, Watt was seen working hard in the gym, flipping a 1,000 pound tire and working the push sled.
