The NBA game was bad in the early 2000's. The East had no talent, boring teams like San Antonio and Detroit were competeing for titles. There were inferior and selfish stars like Iverson, Marbury, Francis, Webber, Carter, and McGrady. The only players worth watching were Shaq, Kobe, Duncan, and Garnett.
A few things changed around 2004 and 2005. One, Steve Nash went to Phoenix, and European style ball caught on, and scores started going up. Shaq left LA, which broke up a talent monopoly and brought star power to the East. And finally, and more importantly, young talent started to emerge, like LeBron, Carmelo, Dwight, Dwayne, Chris Paul, Deron Williams, and Durant.
