I got a heapin' helpin' of Vince's voice. He had a weekly TV show in Green Bay back in the 60's and yeah...I remember THAT voice. Just a notch below the sound of my Dad's voice.
Still, as for the pre-game speech itself ... yeah, I thought it was pretty non-descript. I think that it may have been intended to be non-descript. Essentially saying something to the effect that "You are the World Champions. You know what you need to do. Now, go do it."
I mean, he had a seasoned and veteran team that some argued was out-and-out OLD and washed up. Arguably, they WERE old and washed up. Lombardi though, pushed these guys to a level that no other coach could have. That became fairly evident the first season after Lombardi's retirement from coaching.
