It's been my intention to play more in a Flow or Triangle offense, or even 3-2 sort of spacing. Not so much to use someone like Malone effectively, but to make more use of offensively unskilled but defensively beastly guys like Diamond Mutombo, Diamond Wallace, and Amethyst Rodman...and potentially two of them together.
By the way, I was messing around with 3-2 Zone the other night and it seems like there's only one or two actions in it, but they're interesting. One seems to be ballhandler at the wing and the two bigs posting up, simultaneously, at the high and low blocks. Pass into big in the high post, then pass to big in the low post, high post big goes to screen for low post big, then cuts to basket. Very tight spacing, but if you learn the timing really well, could function as a nice play to run with two bigs, especially if they're also good passers.
Aside from steering defender into the screen effectively, and also taking the correct angle to gain ground on the smaller defender, but threaten paint to draw the big defender (and/or the wing defender), one thing that was very helpful to me to understand was the importance of waiting, after penetration, for the roll man to "catch up."
Basically, you can penetrate and get stalled by a defender, but the action is not over, in that the screener may roll to basket after this, and can be more easily hit with a pass. Especially an alley-oop lob.
