I do not base my defense + or - exclusively on whether or not a team shoots 3 pointers.
I also look at where I team gets it points when game planning.
As an example:
| Opponent's Scoring |
| Pos |
Points |
% |
d40 |
| Guard |
32.5 |
44.8 |
-4.8 |
| SF |
11.0 |
15.3 |
|
| Big |
28.9 |
39.9 |
0.1 |
| Total |
72.4 |
|
0.2 |
In the above example, he gets 44.8 % scoring from his guards and 39.9% from bigs .. d40 is difference from 40% (completely Balanced scoring is 40% G, 20% SF, 40% Bigs) .. and that number is used to calculate a recommend + or - just based on points scored. The equation I use is ((Big-Guard)/20) so in this case that would be: 4.7/20 or 0.2 when rounded. So if 100% of the points cam from Bigs, it would recommend -5, if 100% came from Guards, it would recommend +5, if 100% came from SF it would recommend 0. The theory is: most if the time, your guards are shooting jumpers, not LP shots.
That is just ONE input that I use for distro, the second is this chart:

That Basis percentage is FG3A/FGA .. so if a team had 344 3 point attempts and 1147 total FG Attempts, then the ratio is 344/1147 x 100 = 30.0% (really 29.9913). Based on my chart, that would fall into the -1 range, between 25.48 and 31,67
I developed that chart a long time ago by taking 12 coaches that I thought had a handle on the game and looking that their distro's for every game for 5 seasons as compared to their opponents FG3A/FGA to come up with the chart. It is for Man2Man and Press .. for zone .. I subtract one if I am playing 3-2 and add one if I am playing 2-3 to the recommended distro from the chart. So if I am playing 3-2 zone, and if I get a +2 from the chart, I do +1.
I take those 2 inputs and decide my distro .. in the above case, I had 0.2 (which is basically 0) for the scoring and -1 for the 3 point shooting .. so I would play 0 or -1, probably 0.
If I would have had +1 from scoring and -3 from the 3 point shooting, I would likely do -1 or -2, etc.
