I always thought the best way to kill a zone was to hit the open outside looks they give you that causes the zone to come out and defend that outside shot and then dribble drive through the opens. Just trying to beat zone down the floor before it gets set up will cause a coach to have a couple people to break back and stop the drive to the lane before the zone sets up.
I have no qualms with your defense or inside game but the lack of any type of long outside shooting from the two players playing the most minutes int he back court seriously hurts that team.
Rondo and AB arent great shooters. There are plenty of ways to beat a zone. For example the Cs utilized playing from behind a lot to do it.
Strategy - Attack from Behind the Zone
One of the best ways to attack from behind the zone it to always have at least one player in the short corner area.
You'll find that on almost every ball reversal the player in the short corner will be open. Then the wing can pass down to the open player in the short corner.
Once the ball is there, this is a very tough place to guard because at the moment none of the defenders are looking at the short corner player (because he or she is "behind" the zone).
Once the ball is caught in the short corner you have several excellent options to get high percentage shots...
1) If wide open, the short corner player can take one step to the basket for a lay up.
Derozan/Rondo2) The short corner player can shot fake and take it to the hole.
Derozan/Rondo3) The player in the middle can dive to the basket and receive the pass from short corner (this seems to be open for a lay up almost 50% of the time).
LA/Hibbert4) If they double down, the short corner can kick it out for a wide open three pointer.

None of their starters shot 36% from three.
