Masterful strategy of the ravens at the end
As in our Superbowl, John coached to win. He gambled and it worked at the end.
The final sequence also tells me that John was better prepared, or at least was more intelligent in the last 2 minutes.
To me, the big surprise is the game called by Jim Caldwell, very aggressive from the beginning. I think Sean taught Caldwell that you don't win Superbowls just playing by the book.
