Dribble penetration is a necessity against a zone. It was part of our formula for years.
Not really. Rule of thumb is you beat man defense with the dribble, you beat zone defense with the pass. A 2-3 wants you to try to dribble penetrate, because the penetrator will usually find themselves trapped in the paint with no passing lanes out, and either turn it over or take a wild shot. Going baseline against a good 2-3 like Syracuse's is very dangerous because there will be a trap waiting for you behind the backboard. There are diagonal penetration lanes in a 2-3 at 45 degrees to the hoop, but that penetration is set up by good passing using ball reversals, especially using the high post.
If you can get the ball to the high post, the zone is in trouble. If your high post is a good passer, the zone is in a lot of trouble.
Our best zone busting teams had good high post passing from Knight, Voskuhl, Okafor, Thabeet and even Oriakhi. Okafor, Villanueva and Boone would just high/low zones to death, because once the defense's center steps up on the high post, the blocks are wide open. Combine that with good shooting over the top to stretch the zone out, and THEN you can dribble penetrate against a zone, but if the ball movement and movement without the ball is good enough, you don't really need to dribble drive.
