a) 2-3 zone improves the defensive rebounding of all players.
Are you sure about this?
Of course not... how could I be?
Well, I am just as unsure in my theory, but I will toss it out here for the benefit of everyone.
Is it possible that the zone tactics do exactly what they say? As in, 2-3 weighs higher the ID and RB of your SF in the team ratings.
I am not sure this works for rebounding. But look at defense and offense: Exactly 3 players form IS and ID, and the zone tactic is 2-3. Four players form OS and OD, and the zone tactics are 3-2 and 1-3-1.
Rebounding, on the other hand, involves the whole team, so I am not sure what to make out of it. But I've noticed that I don't get as much increase in rebounding from the 2-3 zone as I would have expected if it gave bonus in rebounding to all positions.
Now all this could all be a load of bull, and some of it certainly is. But hopefully it can start a discussion.
