If anybody can confirm... there seems to be more instances where your PF/C defends the perimeter, and when your guards defend the inside. (such that players sometimes guard other positions). Therefore, players that are more balanced are more important?
Yes, the zone defences have been made into excactly that, zone defences. So if you intend to use zones, then yes, it is good to have both ID and OD (and perhaps some SB,HN,RB too)
ok, but sometimes zone defenses work a bit funny.
In my last game, with me playing r&g and my opponent defending 1-3-1 zone, I saw his PG defending on a dunk of my C.
With a 3-2 defense is quite common (2-3 times a game) to have the C defending on 5-6 meters jumper of opponent's guards.
Overall I feel that zone defenses are much less efficient than they used to be with the previous GE.
