Winning in the NBA

Iv'e always wondered how do teams win championships in the NBA? Most critics say that the key to winning an NBA championship is to play relentless defense. But the era of basketball has transformed into a slow physical style of game to a high tempo style of game with all the different athletes today's NBA has to offer. The past teams that have won the NBA championship are teams who play great defense such as the Los Angeles Lakers with their great front line and Kobe/Artest who are great perimeter defenders. The spurs are another team who has won recent championships and they also take pride in their defense because thats what coach pop emphasizes. Along with Tim Duncan to anchor that D. The Boston Celtics are another team who has had recent success and they also rank among the best in their defensive statistics. It has been proven that the "run and gun" teams such as the Phoenix Suns or the Golden State Warriors always fail to win the NBA championship. Is the statement defense wins championships true? I believe so. even the Miami Heat with D wade and Lebron admit that they can't with the championship with just offense. their main focus is on the defensive end of the floor. They will try and use their athleticism and speed to fuel that defense. As of right now I believe the Chicago Bulls will win the championship because they have the best overall team defense out of the remaining four teams. and they have Derrick Rose who is a beast.
