After looking at the video of Wednesday’s 113-107 loss to the Wizards, Nets coach Jason Kidd’s assessment of why his team lost didn’t change. “We’ve got to rebound the ball,” Kidd said after the team went through a film session but otherwise had the day off Thursday. “It’s understanding the importance of when that team misses the first shot, it’s a big part of us being able to get that stop and go down the other way.” The Nets will get a chance to redeem themselves on the glass starting Friday night in Philadelphia against the reeling 76ers, as will starting center Brook Lopez. Kidd went out of his way to say Thursday that rebounding is a team responsibility, and it’s not on any one player to grab all of the boards for everyone else. But it’s also clear the Nets could use their All-Star center — who has developed into the league’s most skilled scoring big — to give them more production on the glass. Lopez enters Friday night’s game averaging 20.6 points on 57.1 percent shooting, but is managing to grab only 5.9 rebounds in 30.6 minutes per game. “Definitely,” Lopez said Thursday when asked whether he needs to do more work on the glass. “No question. “A lot of it’s on me. It’s just a matter of doing my job.” While there’s no question Lopez does clear out the lane for his teammates to grab rebounds — Kevin Garnett, for example, is snatching 18.9 percent of available rebounds when he’s on the floor, per’s stats tool — the Nets would be better off if Lopez could also corral a few more of those available rebounds himself.
