With Thursday's 106-94 victory, OKC became just the third team to sweep a four-game season series against the Spurs since the beginning of Gregg Popovich's first full season as the Spurs' head coach in 1997-98, per ESPN Stats & Info.
The Spurs entered Thursday's game with a franchise-record 19-game winning streak, but they left Chesapeake Energy Arena looking like the second-best team in the Western Conference.
The Los Angeles Clippers may take issue with that statement, as the Clips have won 17 of their last 20 to join the conversation regarding the West's best team.
However, the Clippers won just one of three games against San Antonio this season, while the Thunder accomplished a rare sweep.
The sweep is undoubtedly impressive, but it's important to remember that two of those wins came in December and January, when the Spurs were dealing with a number of injuries. To be fair, the Thunder didn't have star point guard Russell Westbrook for a Jan. 22 meeting between the two teams, yet still managed to beat a hobbled Spurs team by a score of 111-105 in San Antonio.
Injuries or not, it's safe to say that no team has ever felt as nervous in the immediate aftermath of a 19-game winning streak as the Spurs do right now.
Of course, only six other teams have ever pieced together such a streak in a single season, and four of those squads went on to win championships.
