Interesting stuff--I love it when BB talks about the history of the game. I never knew that there was a school of thought back in the thirties...forties where if you were inside your 10 yard line on first down, you punted the ball. The same if you were on your own twenty on second down and so on.
He also talked about the kicking game and how PATs are 99% successful and that wasn't how it was intended to be when that rule was put in. He didn't give any specifics about rule changes, including the large amount of touchbacks on kickoffs, but it was clear he thought those plays should have some more excitement put back into them.
Also had some interesting things to say about judging whether or not to run a kickoff out of the end zone not only based on how deep it is but also the hang time.
Worth watching.
