I was just reading about BB, Charlie Weiss', and Romeo Crennell's embrace at the end of the game.
This caused me to remember when offensive and defensive coordinators used to sit in the box. I remember that announcers like Summerall and Madden said that coordinators like to do that because they can see the whole field better.
However, I have noticed that more recently (say 10 years) the OC/DC stand on the sidelines.
What changed?
