Nah, you mean there will be tough defense next season? I doubt that, we are already in a era wherein defense is not being played or it's easy to score basket as compare to the era of the 200's. Players now are more of taking long shots even center unlike before. Definitely though I will agree that it's going to be fun and interesting as there are a lot of transfers like Durant going to the Rockets. But there are a lot of star players that are also out, like Haliburton, and Tatum and Kyrie. So there will be someone to step up with that teams. And then the rookies too, maybe we can see that there will be a close fight for that ROTY award this season.
It’s proven already by current NBA champion and contender that defense matters to win a championship. OKC is the number 1 defensive team when they won the Championship.
All the team that focus on offense was beaten by team that has good defense. The weakness of all offense team is their accuracy drop when they are heavily guarded while the defensive team gets an easy basket due to the lack of defense of the offensive team.
I think many teams already adjusting their roster and adding big men is a must now to increase their defensive strength on the paint.
