The NBA Cup is flying by. Already the quarterfinals are behind us. Now, only four teams remain — the Oklahoma City Thunder, New York Knicks, San Antonio Spurs and Orlando Magic.

The quarterfinals offered fans some incredible contests to determine the semifinalists. The Magic came back from an early deficit to defeat the Miami Heat. The Knicks erupted in the second quarter to take care of the Toronto Raptors behind a 35-point performance from Jalen Brunson.

However, there were also some tough matchups to watch. The Spurs won each of the first three quarters against the Los Angeles Lakers en route to a 13-point win, while the Thunder absolutely decimated the Phoenix Suns thanks to a combined 52 points from Shai Gilgeous-Alexander and Chet Holmgren.

The Thunder are clearly the heavy favorites for this tournament, but they aren't unbeatable. Their singular loss on the season is evidence of that. Can the Spurs play the role of hero, saving the NBA from the Thunder running the table? We'll find out during the NBA Cup semifinals. Here's what to know:
