Forbes magazine last week released its annual study with the valuations of the 30 NBA franchises. Knicks and Lakers topped a list in which all teams saw their value increase compared to 2012. It was a good year for NBA owners. Not that they have many bad ones, anyway - at least when it comes to the basketball part of their business portfolio. We crunched some numbers to see the growth in the value of their franchises since they entered the NBA biz. Check the results:
