Win or lose, Jarrett Jack usually does his postgame interviews confidently - shoulders back, chest out and eyes making consistent contact with the questioner.

On Sunday, the Warriors' backup point guard fulfilled his interview obligations with a towel around his neck, his head between his hands and without looking up from the locker room's carpeted floor.

"We just got sloppy with the ball - me, in particular," Jack said after committing a season-high five turnovers. "I feel more personally responsible than anybody. I know everybody is going to say, 'It's a team situation,' or 'You can't point to one or two plays,' but I do. I pride myself on being able to get good shots when it's necessary and making the right decisions late in ballgames."

Jack was bold enough to take the brunt of the blame, but there was plenty to go around after the Warriors' colossal, fourth-quarter meltdown led to a 116-105 loss to Denver in front of a subdued crowd of 15,861 at the Pepsi Center.

After taking a 10-point lead late in the third quarter, the Warriors opened the fourth with a comedy of errors that included turnovers, bad shots and silly fouls. The Nuggets opened the fourth with a 19-2 run, a 4:23 stretch during which the Warriors committed four turnovers and went 1-for-7 from the field while allowing Denver to hit all seven of its shots.

All told, the Warriors lost the fourth quarter 37-18, getting beat 22-6 on points in the paint and 10-2 on fastbreak points as the Nuggets turned seven turnovers into nine points.

"We gave them life by being careless with the basketball," Warriors head coach Mark Jackson said. Denver "is a team that feeds off of that. They got it going in transition, and they hurt us. That's not our brand of basketball, defensively or offensively."

The Warriors (23-13) had won five of their past seven, but they've lost three of four to the Nuggets this season and 16 of the past 18 in Denver. The Nuggets (23-16) have won five straight overall and 12 of their past 13 home games.
