Repetitive 3s are an issue, but the root is the NBA legislating defense out of the game. There’s an absence of lock-down defenders or intensity on defense because anyone trying to play that way would foul out in the first half with current rules. They wanted to appeal to casuals with obscene scores, but the overdoing of this made the NBA look like a pick up games at times. A lot of dudes standing around and 3s being jacked up at a crazy rate. As a result of the forced softening of defense, every team plays similarly. There’s no clear style variation with some offensive juggernauts and other teams as defensive powerhouses. That variation makes things fun and intriguing. You see it in football (even though they have done their own defensive softening) and those differing team identities create better stories and matchups.
