They need to fix rebounding in the new engine with zone, period, to make it viable again. The FG% drop has meant more rebounding chances and thus too big of a penalty against the zone.
Aside from that, it helps to either have a PF or a SF with good Ath/RBD at your 3 spot. the 1 and 2 spot, I haven't noticed a big difference either way, because guards don't rebound much in HD, in comparison to real life.
