The NBA playoffs technically start for the Charlotte Bobcats in two weeks. But tri-captain Gerald Henderson’s message, following Saturday’s post-season clinching 96-94 victory over the Cleveland Cavaliers, was a good kind of greedy. “Wednesday we’re playing (sixth-place) Washington. We’re going after them,” said Henderson, who made two huge jump shots in Saturday’s overtime victory. “That’s a playoff game.” The Bobcats (39-38) are in the playoffs for just the second time in franchise history. They did it the hard way, trailing the Cavs for much of the second half and portions of overtime. Cleveland point guard Kyrie Irving was spectacular with a career-high 44 points, but even he missed a huge 3-pointer in overtime. Other than Irving, this was an ugly game for both sides, with neither team reaching 40 percent from the field. Center Al Jefferson found that appropriate on the night the post-season was clinched. “Our legs weren’t under us and our shots weren’t falling. But we ground it out,” said Jefferson, who finished with 24 points and 15 rebounds. Jefferson was essential to the Bobcats’ turnaround from two seasons that added up to 21-120. He signed as a free agent in July, providing a go-to scoring option this franchise had never really had before.
