Tiafoe bests Donaldson in NBA argument

The only outlier so far seems to be Jon Wertheim, who claims to be a "Lifelong Golden Knights fan," even though it's only Las Vegas' first season as a team.

Andre Agassi and Steffi Graf might have taken Wertheims' side, if they weren't above this kind of drama.

Tiafoe's French Open campaign ended on Monday against Sam Querrey, while Donaldson is into the second round where he'll take on Grigor Dimitrov.

Mark one in the win column for Frances Tiafoe, who gets to have the last laugh in the latest installment of his ongoing NBA debate with Jared Donaldson.

Donaldson was feeling confident about his beloved Boston Celtics' chances of advancing to the NBA Finals on Sunday, but Tiafoe rained on his parade, saying, "You're gonna wake up very disappointed tomorrow morning with this Game 7 loss to the Cavs."

Donaldson rebutted Tiafoe's prediction before the game, adding in the jab that Tiafoe's team, the Washington Wizards, was already out.

But it turned out Donaldson's team would get eliminated at the hands of LeBron James and the Cleveland Cavaliers.

As unfortunate as that result was for Donaldson, it delighted Ohio native Nicole Gibbs.

Nick Kyrgios, perhaps tennis' most prominent Celtics fan, has been silent so far on social media about the loss.

Tiafoe has also been having good luck in the NHL playoffs, with his favorite team, the Washington Capitals, in the Stanley Cup finals starting on Monday. Tennis Channel's Brett Haber has been equally excited about the prospect of a Washington championship.

Haber and Tiafoe are both so excited, it was hard to get the words out.

Steve Weissman and Denis Kudla showed their support.
