Let me start by saying I grew up in the midwest and have never been any closer than at least 6 hours away from a franchise. To people who can't relate to that, you don't know how good you have it.
The very first NBA basketball that I ever remember watching was the 1991 NBA Finals between the Chicago Bulls (with MJ) and the LA Lakers (with Magic). I knew about Jordan, I knew about Magic, and as is nearly ALWAYS the case with me I go with who I perceive to be the underdog who is many times the less-hyped one. Jordan was ridiculously hyped so I cheered for the Lakers. Of course Jordan winning that championship was just Insult #1 in a long line of insults that made me never like Jordan. I stayed with the Lakers even after Magic's famous press conference (and loathed AC Green for saying that he wouldn't want to play with Magic on the Dream Team) and after he retired--the first time. I actually lost my voice screaming at my TV for the massive underdog Lakers in that colossal 5 game series against the Phoenix Suns in 1993. My hatred for Phoenix after they pulled the Lakers series out followed through until they met up with an upstart Sonics team featuring a high-flying, thunder-dunking Shawn Kemp who took Phoenix to 7 games.
The 1993 - 94 season was the changing of the guard from the Lakers to the Sonics, as Laker players got old and retired (Worthy) or left (B. Scott). Also it helped that one of my Lakers, Sam Perkins went to the Sonics. I stayed with the Sonics through good (Finals appearance) and bad (stupid Denver!) until they began dismantling the team circa 1999 starting with the 3 way trade that sent my favorite player, Shawn Kemp, to Cleveland.
When Seattle got rid of George Karl and Milwaukee signed him, I loosely became a Bucks fan for a couple of years (the teams with Ray Allen, Glenn Robinson, Sam Cassell, and Darvin Ham). But really from the period of the lockout (1999) until 2002, I didn't follow the NBA religiously like I had.
When Joe invited me up to join the fantasy league in 2002, and I began to take in games to really learn about the players in the league again: I completely fell in love with the games of Manu Ginobili (a rookie) and Andrei Kirilenko (a sophomore). San Antonio had been a champion, a contendor in the league; Utah, an up and coming young squad starting over post Stockton/Malone. What does Skander do, root for the underdog. The Utah Jazz have been by team since.
