Do you have experience with 3-2 with high SB and low ID (on interior defenders)?
What's inferior for you? I played with bigs SB>ID, but the difference in skills was never higher than 2 skill points.
With a low ID and high SB, you go in for a trade of. The low ID will force more actions against this defender and with the high SB he will stop them. This player will have a lot of defense actions and blocks, but also a higher amount of fouls. At some point you could find yourself too weak. If the ID is too low, the defender will be outplayed and has no opportunity to try a block. So you have to keep your player in balance (compaired to the opponents).
My rule is, that there should never be more than 2-3 skill points difference between my players and the opponents. e.g. a IS 15 C has to be defended by a ID 13 player. A lower skill is too weak (for me). With a high SB (15/16) you could still compensate a lot, but there will be more undefended actions.
