NHL Commissioner Gary Bettman might not yet have anything definitive to say about expansion, though he does have a fee in mind.

How's $500 million sound?

Without committing to what the price might be, Bettman told a meeting of Associated Press Sports Editors on Friday that he's consider a half-billion dollars a reasonable figure.

That would be a significant increase from the $80 million price tag Nashville, Atlanta, Columbus and Minnesota each paid the last time the NHL expanded in the 1990s.

Bettman cautioned that the fee will be determined by the league's Board of Governors, and the time for that discussion has not yet arrived.

Groups in Las Vegas and Seattle are interested in landing NHL teams.
