The New York Giants will make their "Hard Knocks" debut this year on the long-running HBO docuseries, the network announced Wednesday. "Hard Knocks: Offseason with the New York Giants" will premiere on July 2. The Giants are preparing for their 100th season. The franchise opting to take part in this series is a headline unto itself. After all, co-owner John Mara made his stance crystal clear to the New York Daily News back in 2010. "That announcement will come," Mara said at the time, "when I'm next to my father in the Gates of Heaven cemetery." Well, Mara is still alive and "Hard Knocks" is calling as the Giants prepare for their centennial season.
