I see much improved offensive ball movement and off-ball player movement this season and I think an overall better defensive scheme. It isn't always perfect, but it is much better and less predictable in both cases. I think Mazzulla and the rest of the coaching staff deserve credit for this.
As to the quantity of 3s, I am still not sold that there is a magic number of them or whatever. Maybe there is, I just don't know. But if the 3s are generated kind of organically through good ball movement and players moving without the ball, then I am not sure it matters whether it is 30, 40, or 50 3-attempts. It is more about what the defense if giving you. If there are 50 good 3-point attempts, great, take them, but it doesn't seem right to try and artificially force shots to get up to 50.
