As the 2013 Super Bowl approaches, it's time to watch Vince Lombardi give a ten minute lecture on his favorite football play. If you're like me, you prefer to skip the introductory content that encumbers many Youtube clips, so just begin watching at 1:08. You'll enjoy seeing Lombardi start to go crazy as his lecture continues. And this is actually just the first of several Youtube lectures by Lombardi on the same play.
Along similar lines, here's an interview with Jim Ringo. He played center on Lombardi's Green Bay Packer team until Lombardi got rid of him because he wanted more money. Ringo looks like George Washington in this video and seems very composed, but he had to be an extremely aggressive player in order to make up for his lack of size. He was also a fervent anti-communist.
