The 4 teams to make the conference finals were the 4 teams with the highest 3PR Rk|Team|3PAr|
:--|:--|--:|
1|Houston Rockets|0.466|
2|Cleveland Cavaliers|0.37|
3|Boston Celtics|0.367|
4|Golden State Warriors|0.365|

And the rockets almost beat the warriors.  Why hasn't a team tried to just shot a 100 3s a game. Just go all out 2k ball. 3s will likely result in more offensive rebounds which leads to more possessions=more 3s.
