The sport with the most parity...is baseball?

Since it's impossible to even watch the Weather Channel without hearing about NBA free agency, I'm going to promote the MLB a little bit right now.

John and I were talking about the salary cap in the NBA and how impossible it is to understand. And when you think about it, does it really work? Isn't the point of the salary cap to give teams an equal chance to win? Let's take a look.

NBA Championships since the 1999-2000 season

1. LA Lakers- 5 (2000, 2001, 2002, 2009, 2010)
2. San Antonio Spurs- 3 (2003, 2005, 2007)
3. 3 Teams tied with 1- Detroit Pistons (2004), Miami Heat (2006), Boston Celtics (2008)
   

Now take a look at the World Series Champs since 2000

1. 2 teams tied with 2- NY Yankees (2000, 2009), Boston Red Sox (2004, 2007)
2. 6 teams tied with 1- Arizona Diamondbacks (2001), Anaheim Angels (2002), Florida Marlins (2003), Chicago White Sox (2005), St. Louis Cardinals (2006), Philadelphia Phillies (2008)

So whenever the Yankees "buy a World Series" everyone complains that the MLB needs a salary cap. But is it worth overhauling the entire system if it's not even working in other sports?
