Teams I've coached do two things: run, even after a made basket; and press - almost always.
The 2-2-1 zone (no one on the in-bounder; steer the pass to the desired player; trap, causing errant passes and TO's to second line - athletic - defenders; never foul; take away the sideline). I could count 4 occasions where we overcame deficits of 20 or more in one quarter...and so I came to use it all the time.
We spent 20 minutes on it 6 days a week for months...every season. Underclassmen actually showed up expected to know the nuances of our press.
The problem in the NBA is court size. By spreading the floor, filling passing lanes, looking ahead, and attacking - it's pretty easy to beat a press. And the pressing team is extremely vulnerable. I used to PRAY for teams to press us.
Ricky,
I always found the 2-2-1 zone press to be absolute mincemeat to a point guard who is worth his salt. A point guard that will attack this press with abandon, pushing the ball strong to the middle of the court, tends to force reaction by the second line - and at that point, the press is effectively beaten. And even when the press generates a turnover, I don't feel that the d-to-o transition is nearly as smooth and quick.
My preference - stealing a page from the '83 Sixer team - is the 1-2-1-1 full-court zone press. Granted, there's a LOT of pressure on the half-court guy (1-2-*1*-1), and that guy will make or break your press. The reason I like this press is that a point guard isn't going to just run through it. Now granted, it's a whole lot easier when you've got a Bobby Jones playing that half-court spot, but that press is devastating, simply because of the amount of pressure applied on the primary ball-handler. And when offense makes a mistake, you're in a very good court balance for transition offense on the fast break.
The 2-2-1 is a whole lot more common these days than the 1-2-1-1, but I've always felt the 1-2-1-1 forces higher defensive tempo (meaning better transition basketball after the play), applies more pressure to the offense, and forces faster (and less precise) decisions by the offense. In short, the mistakes made against the 1-2-1-1 are not only more frequent, but they're also more COSTLY.
I'm actually getting ready to start up for coaching at the Show-Me State Games again. I'll have to check out the article - see what the going theories are these days.
