PB value is not a good statistic to use.

The semi-lousy players who had a lot of PA's get PB values totally out of whack with their real value. All you will do is make everyone drop these guys from their roster, but they should be an integral part of the game. They played a lot in REAL LIFE because they had value and they should get usage in PB.

Using PB values to evaluate team potential you create artificial value that is even worse than it is currently with the overemphasis on platooning.
