Houston Rockets Chief Executive Officer Tad Brown addresses his role overseeing the sale of the National Basketball Association franchise owned by Les Alexander. Brown says there's been a groundswell of interest from around the globe, including China, where thanks to former All-Star Yao Ming, the Rockets are the most popular NBA team. Brown says it took Yao about 60 seconds to call after hearing the Rockets were on the market. He also talks about what drives the team's valuation and whether the eventual sale price could eclipse the record $2 billion that Steve Ballmer paid for the Los Angeles Clippers.
