As I understand it, this is something that always happens (because the press core has to take a longer route to the pr room) when leaving the locker room. And I believe that Coghlin's presser ran longer than expected on that day.
Eli will never have the mental toughness of his brother. He's a guy that will show flashes, and always be just on the cusp of greatness, but in the end, his mental weakness will shine through. That's how I see it anyway.
