Jameer Nelson must feel like he's caught in a time warp. A ghost still haunts him. Chauncey Billups, his old tormentor from the Magic-Pistons playoff days, is visiting him again. Nelson was minding his own business when Billups showed up Tuesday night, wearing a New York Knicks uniform. He at least was separated by a conference affiliation and a couple time zones when Billups was tucked away in Denver. Now Billups, alias "Mr. Big Shot," was facing him for the new-look Knicks at Amway Center. "It's that rivalry…Orlando-Detroit," Nelson said. For a while, their rivalry looked one-sided as it often has been in the past. Their duel at halftime read Billups 16 points, Nelson 3, and it was Detroit deja vu. "I think I'm a lot craftier now," Nelson said. Nelson had a large smile on his face, finally able to emerge with a victory over his nemesis. He scored 23 of his 26 points in the second half and 14 in the final quarter, including straight 11 points in a two-minute stretch when he helped the Magic push a 3-point lead to nine.
