I refuse to believe that there's only one style of basketball offense that can work anymore. If this is the new normal and teams have to shoot 40+ threes per game to stay competitive I'm going to strongly consider abandoning the NBA as a league I care about. At least until something changes. It took almost 30 years but MLB did eventually abandon the "all homers all the time" style of offense which started in the late 80s and bring back base stealing so there is hope. Something is going to have to change with the rules though because this shooting arms race is not course-correcting on its own.
It's not necessarily that a few teams shooting only threes is boring. We had D'Antoni style offenses for quite awhile and it was interesting seeing what happens when they faced off against a grind it out defensive minded team. It's that all 30 teams have committed to the same offense which makes this situation intolerable to me. When I watch basketball I want to see a chess match of mental strategy and physical skill not a shooting warmup drill performed with a shot clock and referees.
I generally agree with you (I think), in that I don't believe the opposition 3PM would be as big of an issue if we were making up for it somewhere else on the court.
I could only watch the first half of the Brooklyn and OKC games - but - aside from a few possessions - those teams got whatever they wanted. Letting them score 30+ in each quarter is Walton era defence. Brooklyn was especially frustrating in that they had one moderately talented guy who obviously wanted to take every shot, but their team had one turnover at the half.
On offence, what are we doing? We don't pass as much as the beam team, are near the bottom in assists and potential assists, don't seem to attack the rim that often, don't use Sabonis as a facilitator as much. Murray has been in a bit of a funk, which I am OK with because it happens, but asking him to create for himself off the dribble from the top of the key is not how I think he will break out of it.
Most concerning though is we don't look like we are having much fun. Maybe we are tired, injured, and in a bit of pain. And when we get a couple of wins the ball will move more and fall through the net more. Earlier this year we had the 5th best offence and maybe 11th best defence. We had a 10 game stretch where we were 7-3 with some close losses.
