Tim Duncan knows about Sunday's fourth quarter and the confidence the Cleveland Cavaliers might have gained from their rally. He knows Quicken Loans Arena will be loud and unfriendly tonight.

He knows what happened to the Dallas Mavericks last season when they won the first two games of the NBA Finals, then hit the road, and he certainly hasn't forgotten what happened two years ago when the Spurs nearly met the same fate in Detroit.

But Duncan knows something else, too. How he and his teammates feel heading into Game 3 of the Finals.

"We're confident," Duncan said. "We're going in there to get to four. However long it takes."

While the Spurs led for all but 1 minute, 41 seconds of the 96 minutes in the first two games, they were similarly impressive while taking a 2-0 lead in the 2005 Finals against the Detroit Pistons. After walking into the Palace of Auburn Hills, they lost the next two games by 17 and 31 points. Only Robert Horry's heroics in Game 5 prevented them from returning home in a 3-2 hole.

"It was really embarrassing," Manu Ginobili said. "So, hopefully, especially the guys that were in those Finals, learn from that and we are more humble going into these games."
