The Portland Trail Blazers rank No. 15 in Forbes' 2013 NBA Franchise Valuations, worth an estimated $457 million. The team was estimated to have lost $10 million on the year. In 2012, the Blazers ranked No. 13 with an estimated value of $370 million.

Here's the Blazers' blurb.

The Trail Blazers stumbled on the court last year, finishing with a record of 28-38, after three straight playoff appearances. Fans still flocked to the Rose Garden as the team had the second-highest attendance in the NBA, averaging 20,496 fans per game. The Rose Garden is one of the few NBA arenas without a naming rights deal. Team president Chris McGowan hopes to have one secured over the next year in a deal worth $2.5 million annually. Team owner Paul Allen, one of the wealthiest men in the world (net worth: $15 billion), owns the Rose Garden after buying the building out of bankruptcy in 2007.
