One of the issues with a 2-3 zone is that it removes defenders from key rebounding areas/position.
It's MUCH different than man-to-man. You almost can't blame a guy. You're not guarding someone the same in 2-3 because you're also responsible for the NEXT move/pass on the offense. What it means is the Center is often out of position to rebound, particularly when the offense overloads one side.
Coaches always said to me that "more than half" of rebounds end up on the other side of the basket (which is why having Melo and Warrick in 2003 was so HUGE in rebounding...the 2-3 is lights out if you have 6-9 and 6-8 who can rebound on either side).
I try not to be critical of Boeheim since he's had over 900 more Div 1s than I have, but it does drive me crazy when he blames players for being out of position on either D or Rebounding when it's the 2-3 zone's fault. I mean, what kind of defense occasionally has Keita flying out to the corner to defend a three? It happens with 2-3 zone. Similarly, teams can get a good shot if they overload, it's just math (picture Fair over in the corner with noone to guard).
Yanking guys for being out of position, when its caused by the zone structure, is a real developmental issue with this program...you can actually see the resentment on behalf of the guys getting pulled. My issue is the architect of the 2-3 should know it's limitations/percentages and not blame the individuals when the 35% happens.
