Talk about a loaded question. Respect a coach for knowledge, success, humanism, leadership, or wardrobe (e.g. Chuck Daly)?
Great coaches exist in many sports, such as Jack Clark in rugby, Bill Belichick in football, Jose Mourinho in soccer, and so on. Someone mentioned Zeljko Obradovic in European basketball. Let's examine his tactics, using a Chris Oliver YouTube video breakdown via Basketball Immersion.
The most "efficient" use is probably to watch it through and then revisit areas of interest. For most of us who coach "young" players, it's advanced and time is better invested on player development. But education includes technique and tactics.
1. "Flat angle screen prevents aggressive coverages."
2. Communicate to baseline cut and drift to create space for ballhandler.
3. Reshape spacing with flare and pop.
4. Slip to punish hedge.
5. Maintain great spacing to punish tagging defenders.
6. Attack into icing defense, read help, and reverse the ball.
7. Punish tag by lifting (also "the ball is a camera")
8. Punish tag with skip past and early decisions
9. Drop coverage opens pop.
10.Fill spaces behind drives to create long closeouts.
11.Relocate (e.g. negative dribble) to improve attack angle
12.Swing and seal

Lagniappe. Models help us understand the world. For a better understanding of models, consider taking the free "Model Thinking" course from Coursera and Scott Page of the University of Michigan.
Why should we care? Coaching youth teams, I mentally modeled "Draft Choices." Players could be "Lottery Picks, First Rounders, Second Rounders, and Free Agents." Success relates to the talent available in a 'semi-quantitative' way. If our team has a couple of first rounders on the floor and the opposition has four, it's a struggle. But if we have free agents up against a mix of first and second rounders, it's probably a slaughter. It's another way to remain sane when we're up against it.
