Game 1 of the Finals saw the Spurs fall 95-105 to the Knicks on their home court.
In that game, two fans near the court directed crude and offensive "flopping" comments at Brunson late in the contest, prompting an NBA investigation...

In this matchup, Brunson suffered two injury scares (a knee collision and a stepped-on ankle), but he persisted until the end and took responsibility. In about 37 minutes, he shot 12-of-31 from the field, contributing 30 points, 3 rebounds, and 2 assists. He hit several crucial shots in the fourth quarter. This 2018 second-round pick (43rd overall) is emerging as the NBA's next superstar.

On the other hand, the Spurs' starting point guard—at least their highest-paid player—Fox, signed a four-year, $222 million maximum contract extension last summer. However, his performance in Game 1 of the Finals was extremely disappointing. Starting and playing about 38 minutes, he made only 3 of 13 shots, finishing with 7 points, 4 rebounds, 5 assists, and 3 turnovers. He even underperformed compared to rookie No. 2 overall pick Harper (who shot 6-of-10 for 16 points and 8 rebounds).

Looking at Fox's entire playoff run this year, he has fallen short of expectations. Averaging 32.9 minutes per game, he has posted 15.9 points, 4 rebounds, 5.9 assists, and 1.2 steals, with shooting splits of 42.4%, 29.5%, and 72.2%.
NBA reporter Kevin O'Connor commented: "Harper should take over Fox's minutes in the remaining Finals games, and he should be playing close to 40 minutes per contest. "

In short, Fox is under intense scrutiny. It's clear that this offseason he will be deeply involved in trade rumors—even if the Spurs win the championship this year—mainly because, as mentioned above, Harper seems capable of replacing him.

However, given Fox's expensive and lengthy contract, the Spurs would need to find a "sucker" willing to take it off their hands.

Finally, it's worth noting that the Knicks have won 12 straight playoff games this year, matching the 2017 Warriors (15 straight, won the title) and the 1999 Spurs (12 straight, won the title). You know what I mean. *Insert doge meme here.*
