Usually it’s point guard Kemba Walker’s job to assist center Al Jefferson. This time it was the other way around.

Jefferson heard Walker scream, “I’ve got this one!” on a late-game rebound. Jefferson wasn’t sure what all the urgency was about until after the Charlotte Bobcats’ 91-80 home victory over the Orlando Magic.

Walker needed that rebound to complete the second triple-double of his NBA career.

“Ohhhh,” Jefferson joked of Walker’s board, “so that’s why you’re interfering with my business!”

There’s a lot of post-game levity in the Bobcats’ locker room these days. It’s a very different place from the previous two seasons, when this team went 21-120. Now they’re back at .500 (38-38) for the first time since late November and within striking distance of their second playoff berth in franchise history.

Though the seventh-place Bobcats won, they didn’t pick up any ground on the sixth-place Washington Wizards, who beat the Knicks in New York. But .500 this late in a season (the second time in franchise history) still felt good.

“We fought hard to get here,” said Walker, who suffered through the 7-59 season as a rookie.

Walker finished with 13 points, 10 assists and 10 rebounds. One of the first things coach Steve Clifford told Walker and fellow guard Gerald Henderson last summer was they had to rebound better for this team to succeed.

“If I can help rebound,” said the 6-1 Walker, “I think it makes the bigs’ jobs easier.”

This game should have been easier than the last 15 minutes turned out. The Bobcats had as much as a 21-point lead, but the Magic (21-55) whittled that down to seven. Though Orlando was missing center Nikola Vucevic (sore Achilles tendon), the Bobcats struggled to defend Magic guards Victor Oladipo (21 points) and Jameer Nelson (11). Those two combined to make 13 of 29 shots.

“We have struggled with these guys for whatever reason,” Clifford said of the Magic splitting four games this season with the Bobcats.

The Bobcats lost in overtime in Orlando last week, a setback that troubled Jefferson.

“No disrespect to them, but that’s a game we should have won,” said Jefferson, who finished Friday with 29 points and 16 rebounds. “We gave it away.”
