Harris hurting as Nets brace for Florida trip

ORLANDO, Fla. — Talk about your buzz kill.

The Nets had scored two rousing, come-from-behind victories before, understandably and forgivably, getting trounced by Miami. Then came Charlotte. Winless Charlotte.

The Nets on Wednesday had a 10-point lead with 4½ minutes left. Charlotte is no longer winless.

Now the Nets play the Magic tonight and the Heat in Miami tomorrow, with Devin Harris questionable because of a sore shoulder.

“We’re not sure yet,” coach Avery Johnson said of Harris’ availability. “Tim [athletic trainer Walsh] said there’s a possibility [he plays], but until we get there, see how he recovers, then we’ll know. He didn’t do anything [at practice].”

Remember all those good feelings? Currently, they are comparable to the emotions when you wipe down that supposed antique bauble and find “made In China” stamped on the underside.

“It was tough. We definitely fought. We just came up short,” Brook Lopez, paired in tonight’s key matchup with All-Galaxy center Dwight Howard, said of the 85-83 defeat to the Bobcats. “But that game is behind us, and we’re really looking to go into this weekend and picking up one of these games.”

They’ll see Orlando, which has beaten teams by 29 and 42 points. And the Heat, who beat the Magic by 26. Good luck. Especially with Harris likely to be less than 100 percent, though he intends to play.

“Sprained AC joint. Nothing serious. I expect to play,” said Harris, who sat practice yesterday with a sprained left shoulder suffered in the third quarter Wednesday — he returned to play the fourth quarter.

“It’s a little bit sore,” he said. “It was sore [Wednesday]. I expect it to be better [tonight]. Go from there. It’s not really restricting me.”

Should Harris be forced to sit, Johnson, who started Troy Murphy at power forward against Charlotte after his injury absence from the first three games, said backup point guard Jordan Farmar is the choice to start.

Johnson is a realist so his goals for the Nets are practical. He would love victory, but what he’s looking for is continued improvement, achieving small steps.

“I want to see good body language. I want to see us attack. I want to see us look like we belong, that we’re going on this as a business trip and we’re going into the game thinking that we have a chance to get better, a chance to win, a chance to execute our offensive and defensive strategies,” Johnson said.

So he’ll look for an attacking mentality, hard fouls, better execution. He’s not surprised where his team is, he said, and he’s more concerned in how it gets to the next level. And he hopes to see Lopez’s continued development, facing a stud like Howard.

“Dwight Howard right now is in a stratosphere of his own, especially on the defensive end, especially the way he plays pick-and-rolls and his physicality,” Johnson said. “So Brook is still maturing and he still has a ways to go, but we like the level where he is right now.”

Lopez also suffered a left shoulder ailment Wednesday. He said there was only a little soreness and he felt fine. . . . Lopez has faced Howard six times. The Nets are 1-5 in those games. Lopez has averaged 12.2 points, 7.8 rebounds, shot .462 (30 of 65). Howard has averaged 20.0 points, 14.8 rebounds, shot .594 (41 of 69).
