The problems of SB, as we know, are the impossibility to see its advantages in the matches and the high increase that it gives to the players' wages. About the first, i had an idea. Why not add another defense in the post match ratings (i don't know how are they called, i mean the ones where you can see the level of your outside offense, rebounding etcetera...). I think that in real life there are 3 type of defense required: inside defense (contain the man in the low post, under the basket, really near it = ID of C, PF and maybe SF, it depends from the opponent), perimeter defense (try to not let the opponent penetrate, do pressure, steal balls and disturb his 3 pointers = OD of PG and SG, maybe SF and sometimes PF) and the last one, the one that i want to suggest, driving defense (use the body and hope that your taller mates help you = ID of the direct defender (PG if opponent's PG is penetrating, SG if opponent's player is a SG etcetera...) and SB of the helper (PF or C) who can try to stop the ball. This way we can know what's the best tactic to use for the offense (LP if the first defense is low, motion or R&G against the second and LI for the third. This way can make SB useful and help defending against LI.
I'm sure i made some grammatical/typing mistakes, sorry for that. I hope the message is clear.
