It's the storyline.
Brady's greatest comeback ever!
He does absolutely nothing but look terrible for 59 minutes, then suddenly, the other team always throws up all over itself (Saints RB going out of bounds untouched before getting the first, Cardinals suddenly fumble a simple pitch play) and magically, Brady is suddenly unstoppable.
It's too convenient.
So you can laugh all you want, but these stories always end with golly gee genuine Tommy holding a trophy
