I'm such a fan of this style of play. When I was an assistant coach, I advocated for versions of this. When I was a head coach, we did this. When my former players became coaches and asked me for advice, I encouraged them to do this.
There just are so many advantages.
-- You are imposing a tempo at which you are used to playing but your opponent usually is not. It's like the old days of vinyl records. A record that sounds perfect at 33 1/3 sounds awful at 78. Eventually you break the record, the player or both. It's hard to play at this pace if you are used to playing at one that's more controlled.
-- It's very empowering. Making the other guy play your style feels like a win in and of itself. It makes you more confident.
-- Three or four of your players only have to play 18 seconds of halfcourt defense, because you've made the other team burn 6 or 7 seconds just getting the ball past the timeline.
-- It's a natural style. You don't have time to think. You have to react. Solid fundamentals are rewarded in man-to-man defense or ballhandling. If you like playing basketball, it's an easy way to play.
-- The other team might get open shots, but they aren't going to get them where they're used to taking them. Most pro players are used to practicing getting to a certain spot on the floor where they make almost everything. If you get them off that spot, even the best are somewhat mortal. Just shoot 17 footers from around the elbow vs. on the baseline, and you'll see it's a very different shot.
-- Constantly attacking makes you feel stronger.
-- Players get tired, so it makes them less likely to worry about minutes and improves the playing rotation, camaraderie and depth. They might play 26 and feel they played 30-31 because ....
-- There are a lot more possessions. It takes the pressure off missing a shot because you know you're going to have more chances to make up for that, or you're going to have a chance to make up for it on the defensive end.
-- If you have better athletes rather than better basketball players, it gives you more chances for that athleticism to manifest itself.
-- You get more shots per game because you're going to get steals and you're going to get offensive rebounds.
-- The other team is forced to box out every possession, which puts it on its heels and makes it passive and less likely to break out in transition, because the players have no idea where a defender might be flying in from. The team employing this style is coming from all kinds of unorthodox angles and timing.
-- Attrition. The other team, which is used to playing more deliberatively and with a tighter rotation, wears down. Often, that is going to result in them coming up short on shots later in the game or being just a little bit slower playing defense.
-- There's a good chance you're going to get players on the other team in foul trouble because of the additional possessions, the unfamiliarity of responsibilities on either side of the floor and fatigue, so you'll also get more free throws most of the time, if you can make them.
-- As the other team gets tired, you'll get more layups, either from tired passes being stolen and taken the other way or the other team just being unable to process what they have to do defensively when they're physically tired.
-- You don't get overcoached. Players feel agency and ownership.
It's all about being comfortable and making your opponent uncomfortable, which is what I think the Blazers have called it, making the other team uncomfortable in every way. I called it controlled chaos. One of my former players even put that on the team's shooting shirts the one year, complete with a graphic of a tornado in team colors sending a bunch of players from the other team flying around in all directions. Pretty cool. One of my favorite shirts.
