I think that GS is a 2.9 offense because they shoot so many threes they force the defenses to come out of the lane and guard the perimeter. Thompson & Curry shot an astounding 1156 3's last season. The W's shot about 20 threes per game. And incredibly there were 12 teams who shot threes at a higher rate. Houston and NYK shot 3s at an astounding rate of 29 per game. The number guys say that Houston should shoot more. 5 years ago 5 teams shot more than 20 3's per game. 10 years ago 2 teams. The Jazz had a huge increase in three pt attempts last season (17 per game) but are still about 5 years behind the league.
Houston shot an unbelievable 34 3pt attempts per game in the playoffs. The number guys say they should shoot more. The trend will continue . I believe the NbA will eventually have to address this trend like they have addressed other trends....rule changes. But for now the Jazz are so far behind the rest of the league that a McCollum in place of Burks would (5.4 in college vs Burks 1.8 in college 1.4 in NBA) would be a huge advancement.
