Theory behind B and C positions

[jkumpire]

I hate to be so old now, I remember "old school stuff"....

The old timers taught me that "being ahead of the runner" is the important thing, that is why many people are in C even with R3. You may say that you can't be ahead of the runner in C, but many times that run is the important runner in the game, and if there is a play on him at #B, it can be a significant play in the game.

The concepts that are so important in teaching mechanics today, like "angle over distance" and "cover the money play" were not as emphasized as they are now. when I went to school in the 1980's neither of these concepts were even discussed.
