"It has been a given for more than six years that the Suns were better than most NBA teams.

That no longer is the case after they lost to the Los Angeles Clippers on Sunday and dropped a season-worst fourth consecutive game Wednesday by falling 123-110 to the Philadelphia 76ers at US Airways Center.

It is the Suns' longest losing streak since January, but it is hard to see another 30-10 season finish following like it did then. The Suns (13-17) are so bad defensively that they allowed the 76ers to score 27 more than their season average. The 76ers were a 4-13 road team that had not won in the 11 previous times it allowed 100 points.

The 76ers shot 61 percent in the first half and put six scorers in double figures even though they did not have their star, Andre Iguodala, who sat out because right Achilles' tendinitis, and Jason Kapono. That came after the Suns had worked on defense for two days in practice.

Instead, Iguodala's replacement, Andres Nocioni, posted a double-double with season highs for points (22) and rebounds (12). 76ers rookie Evan Turner added a season-high 23 points. He made nine of 12 shots even though he entered the game shooting 38 percent and averaging 6.8 points.

The Suns lost for the eight time in the past 10 games.

"I came from a team where everybody's competing and trying, doing the stuff that Coach is saying," said Suns center Marcin Gortat, who came from Orlando in a six-player trade Dec. 18. "We just totally are changing our rotations. We're not playing hard enough. There is a lot of work in front of us. The positive thing is it can't be worse.""
