Tim Duncan retires with a slew of NBA records to his name. He has the most wins with one team (1,001), most minutes played in the postseason (9,370), most career blocks in playoff history (568) and he owns the majority of the Spurs' record book (points, minutes, rebounds, blocks, games, field goals, more).
With that said, Duncan is walking away from the chance to claim a few more impressive records. Here are five marks Duncan can overtake if he reneges on his retirement and plays a couple more seasons.
Most Games Won (1,001, 3rd All-Time)
Duncan's final season turned out to be the Spurs' winningest season, as the team claimed 67 victories. But the other 18 years were pretty good too, with Duncan's teams never posting less than a .610 winning percentage in a season (50-32 in 2009-10). Duncan played in 1,392 career games and never missed more than 24 games in a season. Only Kareem Abdul-Jabbar (1,074) and Robert Parish (1,014) have more wins than Duncan.
With another season, Duncan would have passed Parish. In two seasons, he likely would have eclipsed Abdul-Jabbar.
Most NBA Championships (5, 5th all-time for players not from pre-1980 Celtics)
Okay, we're kind of tinkering with this category. The first eight players on the list -- Bill Russell, Sam Jones, Tom Heinsohn, K.C. Jones, Satch Sanders, John Havlicek, Jim Loscutoff, Frank Ramsey -- all played for pre-Larry Bird Celtics teams. The Celtics won 14 NBA titles from 1957-1976.
If we start NBA history in 1980 (this also knocks out Bob Cousy, who won six titles with the dynastic Celtics), only Robert Horry (7), Abdul-Jabbar (6), Michael Jordan (6) and Scottie Pippen (6) have more titles than Duncan. There's no promise Duncan could win two or three more titles, but with the Spurs' current roster, he could play ten minutes per game for a title contender for a few more seasons.
Most NBA Playoffs Games (251, 2nd all-time)
It's hard to believe Duncan does not already have the record for most postseason games played, considering he went to the playoffs in all 19 of his seasons and made six NBA Finals. Duncan was actually zeroing in on the record before retiring. With ten final games in 2016, Duncan finishes with 251 postseason appearances. That leaves him just eight games behind all-time leader Derek Fisher at 259.
Had the Spurs made the 2016 NBA Finals, Duncan would have broken the record. One more season, and he could have likely clinched the crown next spring. If it means anything, at 213 playoff games, Tony Parker has a chance to make a run at Fisher's record over the next couple of years. Duncan's 157 playoff wins are second to Fisher's 161.
Oldest Active Player (2nd at time of retirement)
Duncan, born April 25, 1976, was the second-oldest NBA player in 2015-16, barely letting teammate Andre Miller edge him by 37 days. Miller is currently a free agent, and if he doesn't sign anywhere, Duncan will miss an opportunity. Kevin Garnett, born May 16, 1976, can sniff the oldest active player honor.
Duncan can justify his decision if Ray Allen does indeed make a return to the NBA. Born July 20, 1975, Allen has not played since his Heat lost to the Spurs in the 2014 NBA Finals, but he's reportedly interested in joining the Warriors. Allen would become the NBA's oldest player.
Most Years With One Franchise (19, 2nd all-time)
Duncan played all 19 of his NBA seasons in San Antonio, one of three such players to accomplish that feat. John Stockton played his 19 NBA seasons in Utah. But one player registered 20 seasons with the same NBA team: Kobe Bryant.
The Black Mamba was drafted by Los Angeles one year before the Spurs selected Duncan, and Bryant retired this past spring (with a lot more hoopla than Duncan got).
