The NBA and hero worship

I think one of the reasons I don't really care for the NBA is how individual players can sway the balance of the league by themselves. Consider: The Colts are anticipating the loss of one of the most prolific quarterbacks in the league, but instead of this being backbreaking, it's simply a bump in the road on the way to rebuilding. Of course, the team needs defense and younger skill players, but that's the point. They need to build an entire team. There are 22 players that need to be capable starters.The St. Louis Cardinals will be fine despite losing Albert Pujols, and the Angels are better, but not the class of the league because they signed him. The NHL makes roster moves like I change underwear, underscoring the relative lack of importance of an individual as it compares to the team.
If you look a the roster of an NBA team, they have 12 players total. Look at the tumult that was created by Lebron James leaving for Miami. Look at Cleveland without him. Look at the to do surrounding the contract given to Kevin Love. Look at what happened when the last Kevin, Garnett was traded to Boston. One player is 20% of a starting lineup. That's 4 people on a football team.
So given that, I guess it's more justified going after Lebron for his decision, because one player is so important. It also makes a player like Dwight Howard, calling his shots in trade, seem a little tasteless. He will likely lead to the vast improvement of one team (especially if he can get a friend to join him, meaning he accounts for 40% or more of the new roster) and the destruction of his current team, the Orlando Magic.
And that's the rub, I think. How can anyone really say they are a fan of one team, when really, that team's fortune's ride on one or two players? Aren't you just cheering for one player at that rate? You're entitled to like what you like, but I don't think I can ever quite get into the NBA.
