Fantastic reading about that 1961 bunch. I was 10th grader, but I saw a few of those games. I know most of you remember the great D of 1992, but the 1961 D was pretty spiffy as well. The substitution rules of that time meant that a lot of players went both ways.
Still, 5 straight shutouts, and several opponents held under 100 total yards is impressive in any era.
