His Miller Lite commercials are great (a little before my time though!). Up until the end he was pretty articulate. He was on ESPN radio occasionally and I was always impressed with how well spoken he was. In terms of his views on football he was very old school and I really liked that about him.
Here's his Miller Light commercial-man those must have been the good ol' days.
He invented the term "sack the quarterback." There's some great footage of him where he is reaching around offensive linemen, grabbing the QB and dragging him down. If QB sacks where a stat when he was playing then he almost certainly would be an all time leader in that category.
