SAN ANTONIO - The lights went down before the Spurs' starters were introduced for Game 5 against the Trail Blazers, and Julian Champagnie had one last thing to do. With only pyrotechnics and fiesta-colored visuals to light the way, the undrafted shooter launched from the corner and swished. He got the ball back and hit again from the same spot, and then one more time before cutting for a dunk. Moments later, the PA announcer called out number 30, the forward from St. John's. "I did every game," Champagnie said after the final buzzer. "Lindy (Waters III) closes out, and then Dylan (Harper) always passes to me. I do it almost every game. It's not too hard when you know the rim is at, like, once you see it before the lights go off, it's pretty easy. But, yeah, just my little thing to get in rhythm. Tell myself, 'well, you could shoot with the lights out, you can make a shot later when they're on." With a red-hot start and a nose for the boards, Champagnie helped put away the Trail Blazers in Game 5.…
