Based on Dallas and Oklahoma City, both having hosted the NBA Finals in the recent past, the Greater San Antonio Chamber of Commerce predicts the economic impact from Spurs-Miami Heat showdown could generate $3 million to $4 million per game.
Becky Bridges, the chamber's spokeswoman, said that was solely from expenditures for lodging, restaurants and bars.
If so, since San Antonio will host three local games, they could generate a $9 million to $12 million boost in its economy.
"That does not include T-shirts or souvenir sales," Bridges said. "Also print shops making signs and banners are not factored in."
Bridges also said in terms of media exposure, the NBA Finals rank third behind the Olympics and the Super Bowl.
Andres Munoz, vice president of marketing at the San Antonio Convention and Visitors Bureau, said the NBA Finals are seen in 215 countries.
"What's really priceless is that all these viewers all over the world are watching San Antonio," Munoz said.
He also said many will be following international team favorites such as Manu Ginobli, of Argentina, and Tony Parker, from France.
In preparation for its worldwide audience, the AT&T Center is working to accommodate what the NBA needs.
"We really work in tandem with them," said Kenny Hartmann, event services coordinator at the ATT Center. "We tell them what we're capable of doing (and what we're) not capable of doing."
Hartmann said there are a lot of moving parts to make sure all goes as expected.
But he said, "We've done it all before."
