4. Two-way tie: Mavericks and Heat (4 losses)
The Spurs welcomed Luka Doncic to the league with a four-game series sweep in his rookie season. Since then, it's been all Mavericks. Dallas has taken 13 of the last 15 meetings with San Antonio, with the Spurs' last victory coming in April 2021 after DeMar DeRozan nailed a game-winner.
Meanwhile, the Miami Heat snapped a nine-game losing streak to the Spurs in 2018 and haven't looked back. They've won seven of eight meetings since and have swept the last two season series.
San Antonio should have four shots at snapping the Mavericks' four-game win streak next season and two shots at snapping Miami's.
3. Brooklyn Nets - 5 losses
Like almost every other team, the Brooklyn Nets suffered a double-digit losing streak to the Tim Duncan Spurs (14). San Antonio even enjoyed a seven-game streak from 2015-2019, but things have since changed.
Brooklyn now hasn't lost to San Antonio since December 2019, although two of their wins have required overtime.
With James Harden now in Philadelphia and the futures of Kyrie Irving and Kevin Durant up in the air, who knows what kind of team the Spurs will be facing next season. Either way, I'm sure they'll be eager to snap this streak.
