if anyone is interested:
for last years team
3 pt:
37% or 1.11 ppa
6.3 points stddev
-11.4 skew
2pt:
52% or 1.04ppa
8.6 points stddev
5.3 skew
So the only difference is that last year's teams offensive output on the whole was much more up and down...again, i'm not sure the predictive value here...because individual seasons and the tournament in general are such small sample sizes.
