NBA union director Billy Hunter doesn't buy commissioner David Stern's assertion of the severity of the owners' financial woes.

Stern claims league lost $370 million last season, but Hunter responded by saying that the numbers may be off by as much as $370 million.

The NBA's current collective bargaining agreement expires on June 30, 2011.

"I'm preparing for a lockout right now and I haven't seen anything to change that notion. Hopefully I'll see something over the next several months," Hunter said. "As of this moment, it's full speed ahead for me in preparing the players for a worst-case scenario."
