I've always been a huge fan of Popovich. They are big on penetrate and kick and they always have reliable shooters. Helps to have players like Parker, Manu and Duncan as well as always having great shooters and Duncan who is great at realizing a double team is coming kick it back out for the shot, or the extra pass. They also always play solid D and hold each other accountable. I think this might be their year again. I'd also like to add, they always find great shooters. Hill has been great, Bonner and now they have Neal looking like Hersey Hawkins or vintage Dana Barros. I'm jealous.
San Antonio and Utah. Both have great ball movement, their players are in constant motion even without the ball and they play smart. When the time is right, they're happy to run.
Boston wins the right way. LA wins the right way. The kill you in the paint. Much like the Rasheed/Grant/Sabonis era Blazers did. Own the paint, be very efficient, and win the rebounding war every night by a large margin.
