...Neyland was so long ago, and coached such a different game, that I don’t see where comparisons to him are that relevant.
A few folks have made the same point in this thread. I understand and respect it. You're right, in many ways, the game of football is vastly different than it was in, say, the 1930s, '40s, and '50s.
Then again, some things haven't changed at all. It's still a coach and some assistants, recruiting, training, developing and leading a team of young men in direct competition on a gridiron with a weirdly-shaped ball against another coach with some assistants and their own team of young men.
Point is, when you are able to rise above your competition, others more or less like you with pretty much the same tools, when you stand out against them, you're a good coach. The more you stand out, the better you are. Stand out enough, and you're truly elite, a "once in a generation" kind of coach.
And so we
can compare our coaches over time. Not directly against each other. But against the record books: how much did each stand out over his peers?
That makes them legitimately comparable across the decades. I think, anyway.
Go Vols!
