Someone at TNT came up with the ingenious nickname of “Old Man Riverwalk” for Tim Duncan.And not even four straight days in Southern California could dry him out.Duncan hit 10 of his first 11 shots Wednesday night, had 18 points in 16 minutes at one point, and then flipped in two buckets in overtime. San Antonio thus put down the Clippers 111-107 to tie this first-round series 1-1.The Clippers survived an all-out hack attack on DeAndre Jordan to slowly erode a 10-point San Antonio lead in the second half. They also had a two-point lead with the ball, but Blake Griffin lost his dribble and Patty Mills tied it with two free throws. Newsroom GuidelinesNews TipsContact UsReport an Error Duncan turns 39 years old Friday. He has been with the Spurs for 17 seasons now. Paul turns 30 on May 6. Even his memory of Duncan is a little fuzzy.“I was 11 years old, man,” Paul said at Wednesday morning’s shootaround at Clippers headquarters.Paul was living in Winston-Salem, N.C. as Duncan was ruling the ACC from his perch at Wake Forest. That’s quite a haul for the small Baptist school, having one sure Hall of Famer and another possible honoree so close together.“But his nephew and I played on the same AAU team,” Paul said. “I used to go to the YMCA to watch him practice. Then he was drafted No. 1 and he came to visit our team. We were the happiest kids in the world, being able to see a first-overall draft pick and jumping him in the hotel.”Redick lit up the league while he was at Duke, and he grew up in Roanoke, Va. when Duncan was on the rampage. Redick turns 31 in June.“I remember that Duke beat them,” Redick said, with a smirk. “I think that was 1997, at Wake Forest. And I think we tied them for the conference that year. That’s what I remember.”Any non-partisan memories?“What’s weird to think about is that he was basically going to be the No. 1 pick for three straight years. You don’t see that anymore, because the second that a kid decides to go back to school, they (scouts) keep watching him and find something to dissect.”Duncan was a 21-year-old man when he landed in San Antonio. He won NBA championships in his second, sixth, eighth, 10th and 17th years in the NBA, and those happen to be all the championships San Antonio’s franchise has won.Duncan has averaged fewer than 30 minutes per game in four of his past five seasons. But Gregg Popovich said at midseason that Duncan had been the Spurs’ best player by a significant margin.Those who like metrics can find evidence that Duncan’s minutes are as potent as ever. A stat called Total Rebound Percentage, which is an estimate of the percentage of the total rebounds a player corrals, shows that Duncan checked in at 17.9 this year. His figure as a rookie (albeit with David Robinson beside him) was 17.6.Of course, Duncan predates metrics. And calculators. But he never tires of the same old story. On the final possession in regulation, Kawhi Leonard stayed close to Griffin and made Chris Paul take a shot from the right wing, which he missed. That sent Griffin into a self-flagellating frenzy, and overtime loomed.A 3-pointer by the misfiring J.J. Redick tied it at 101-101, but then Duncan got into the lane and sort of pushed in a 10-footer while falling, one of his trademark shots. Mills, who was enormous for the Spurs with Tony Parker hurting and ineffective, then scored on a run-out, and Redick’s bid to tie it with 12 seconds left bounced away.The Clippers lost for a lot of reasons. Duncan had 28 points and 11 rebounds in 43 minutes, for one thing. But one paramount reason was a breakdown by Redick, Matt Barnes and Jamal Crawford outside. They shot 9 for 35 overall and 6 for 22 from the 3-point arc, and Griffin, Paul and Jordan couldn’t compensate.And so the Spurs, who would have been written off as doddering pensioners had they fallen behind 2-0, are back to being sagacious basketball professors. It’s the difference between a car that’s used or pre-owned.But it’s still difficult to fully realize how many rings are on that particular San Antonio tree.
