PS: and you don't need a proficient flow, i have good result with my average till respectable flow, on a high level.
I have had pretty good success with an average-respectable flow this season, too - but only when I don't use an inside offense. Well, unless I go against an opponent with a lessor outside d rating.
Yes, an inside offense against a 2-3 zone certainly works better than an inside offense against man to man. It is because the 2-3 zone weakens the perimeter d, making it easier to hit the short jump shots.
Here is the issue as I see it:
Let's say in a base offense you can put up respectable in outside and inside scoring. If you go to an inside offense, this brings your outside scoring down to a high mediocre or a low average, but pushes your inside offense up to maybe prominent. The trouble is, less than half your shots will actually be inside shots. The rest of your shots will be modified with your crappy outside scoring rating. Many more will be driving shots for your guards - which is usually not good.
Now, if you go outside instead, let's say you can now put up a proficient outside scoring. The inside scoring rating is no big deal - you only get 20-25% of your shots on the inside. Maybe another 20-25% are 3s, 20-25% long jumpers and 20-25% short jumpers. That means 75-80% of the shots are using your great outside scoring rating.
So, to sum up, when you are talking about teams that can post a respectable or higher outside d rating:
man is the new 2-3 zone
push the ball is the new look inside
patient is the new low post
