Suggestion to add a different section for back-ups when setting defensive match-ups for games.
For example, this way you can set your starting PG to play defense on their SF, but can keep your back-up point guard defending their PG. This wouldn't take away any strategy, in fact it could add some, and also allows for more realism.
Maybe it is hard to code into the game, and in that case, obviously don't bother, ha. But if it is easy to do, it would be nice to be able to play your starters out of position defensively without the back-ups having to do the same.
