Hard Knocks Open Thread: Episode Four

We're going up a little early tonight because I know that mostly all of you are pacing around the living room waiting for the second to final episode of Hard Knocks this season. Here's a quick recap of possible storylines:

• James Harrison's arm wrestling competition
• A.J. Green's return to action
• The brotherhood of the defensive line
• Practice at Springboro high school
• Film and sound from the team's preseason loss against the Dallas Cowboys
• It also looks like Taylor Mays and Rey Maualuga head to the Cincinnati Zoo
