Gregg Popovich signed a five-year contract extension with the San Antonio Spurs last offseason, but he doesn't expect to see out the entire length of the deal.

"It's a five-year contract, but the chances of staying for five years I don't think are very good," Popovich said.

The Spurs have been inconsistent in the difficult Western Conference this season.

"This year has been a tough one," said Popovich, whose team lost eight of 11 games at one point and was 19-14 entering New Year's Eve. "We had an amazing schedule, a very tough November and December and we were very injured. So it knocked the hell out of us, to where we're now just starting.

"I told them the other day, I said, 'We're starting the season. We finished training camp and we're in our seventh or eighth game right now trying to get ready. The season is over half done, and we're just rounding into some kind of shape.' So it's been difficult."

Popovich has been head coach of the Spurs since 1996.
