It's the old "era" thing. I think it is very difficult to evaluate how someone who did what they did in a different time would fare if they were starting out today. They are, after all, a product of what they have been, if you think about it.
Tara is a very good coach.
As coaches get older they may find recruiting more difficult, then success is more difficult, which makes recruiting harder, etc., etc. Vivian Stringer has spoken to this in some interview I saw or read. But if they were starting out today, who knows . . .
These are not stupid people and I don't buy into the game "passing them by". It is true that their skill set and their natural coaching styles may not translate as well today as it once did, but Vivian, among many others for example, went to learn the "triangle" when it was a hot thing to do, so they were trying to improve their "game".
