There's something wrong with this picture. Let's see if you can figure it out!
Or if you're more of a moving pictures person, the following visual aid should help explain what happened.
There's Tom Brady dropping back to pass in the end zone and giving up a safety as he desperately tries to heave the ball away with his left, non-throwing hand. It didn't work, obviously, and Brady was flagged for the intentional grounding. You know what intentional grounding in the end zone means! A safety.
At that point the score was 6-2, which seemed kind of fitting considering the half of football. Both offenses were stuck in neutral for much of the half, and we all suffered because of it. But business is beginning to pick up, at least!
