I've also heard a BB say that it seems unbalanced that the SF position is the only position without a single position training slot available to it.
My bad, they said the first half and I added the (incorrect) second half. PFs also need a one position training, but most people don't complain because centers and PFs can mostly interchangeable.
I think the training aspect is challenging to a fault, and the SF GE aspect is a failure in representing the game of basketball.
sf in the GE - you can play a center at SF against an actual SF, with roughly comparable total skills, and be very successful. It's unrealistic.
Now a Sensational ID/OD player would be very neat!
