I found Olson to be unbearable myself. He still talks like a player. He never explained anything.
For example, the big phrase I started hearing more this year was 'game'. Noooooooooobody took the time to explain what it meant like John Madden would do. You know, "Ordinarily, you got these big guys just running through these gaps here...but when we run a game, okay, we get this big guy running to the other hole, and this other big guy running to the other side. This can really mess up an offensive line."
"....great, John. 3rd and 20." And Summerall would just deadpan his reaction to what Madden just said. Good stuff.
