IRVING, Texas - Roy Williams dropped another one yesterday. This time, the Cowboys' clumsy receiver let go of some of the bravado he has clutched all season.

Williams has been confident and upbeat in interviews every week, no matter how much he has struggled on the field - and he has struggled plenty, catching only 38 passes for 596 yards when he was supposed to be Tony Romo's No. 1 target.

The last two games, Williams has dropped key passes that hit him in the hands. The latest one came shortly before halftime at Washington, with no defender near him, and he didn't have another ball come his way the rest of the game.

"That's telling me my quarterback lost that confidence in me and so did the coordinator calling the play for me," he said. "I don't blame them. I blame myself. So I have to get my [act] together and try to right this thing and help this team win some games in the playoffs."

Williams added that his confidence is still high, and he believes he has "the best hands in the league, top three at least," yet he still planned on putting in extra work after practice.

The Cowboys gave up four draft picks, including first- and third-rounders this year, to get Williams from Detroit midway through last season, and immediately gave him a $45 million, 5-year contract extension.

Team owner Jerry Jones said yesterday he still believes his big investment in Williams will pay off.
