A couple of concessions.
1. It was pre-season.
2. Kemba was getting used to new teammates.
3. Kemba was out of sync.
That being said, the Celtics' new scheme is a large part why. We will see a repetitive refrain this season each defensive possession.
1. Offense runs first action. Celtics switch.
2. Offense runs second action. Celtics switch.
3. Offense stalls with first or second best scorer having the ball, who has to create the best shot they can, while all the other offensive players stand and watch.
Here's the cool thing: Brown, Morris, and Smart both can be elite on-ball defenders in isos. Horford and Baynes are elite post defenders. Hayward is underrated. Tatum's length is invasive. Even Irving looks primed to be better this year.
Guys will hit amazing shots against us. Sometimes, scorers will catch fire. But we will consistently hold teams under 100 points.
Jaylen Brown's length and activity will be a big reason why. I love that he can switch 1-4, while being effective and disruptive. That frees Irving and Hayward to do their thing, which should make us a really good offensive team.
