Like the other reply I do
(292602.2)Whats Happn is when you train the PG on C position to training ID and choose only C position to training he have 100% of training.
But, if you choose C/PF, the training is the same if you choose to training only AF [90%]
And other view.
How a PG get successfully IS skill if he play only as PG - a outside position?
The same to a Center to training OD playing in C position - a inside.
There is no way to improve on math by studying history.
