ESPN’s Jeff Van Gundy doesn’t think very highly of the personal research capabilities of NBA players.

During the Thursday night preseason game between the Houston Rockets and the Miami Heat, Van Gundy took a shot at unvaccinated NBA players who claim to be doing their “own research.”

“Just in general, you the know the one that drives me crazy? ‘I’m doing my own research.’ I would like someone to answer this question: What does that look like? You’re doing your own research? Are you doing studies yourself? Are you in the lab on a nightly basis? What’re you doing? I don’t understand what that means. ‘I’m doing my own research.’

“How about this? We got really smart people, a lot smarter than anybody in the NBA who’s already done the research.”

Brooklyn’s Kyrie Irving and Orlando’s Jonathan Isaac are among the most vocal of the NBA’s vaccine holdouts. Irving remains unvaccinated in violation of New York City’s vaccine mandate. Should he stay unvaccinated, he will miss all 41 home regular-season games in addition to a road game against the Golden State Warriors in San Francisco, a city that also has a vaccine mandate.

Irving, Isaac, and NY, other unvaccinated NBA players, will also possibly face criminal charges should they breach quarantine during road trips to Canada. According to Canada’s Quarantine Act, visiting unvaccinated players will be confined to their hotel rooms except to attend “team activities.”

Golden State’s Andrew Wiggins initially said he would not get vaccinated. However, this week, Warriors head coach Steve Kerr revealed that Wiggins did receive the vaccine.

“It came down to get the vaccination or don’t play basketball,” Wiggins said. “I’m 26. I have two kids. I’m trying to generate as much money as I can for my kids and my future. Trying to create generational wealth. Hopefully, it works out in the long run [and] in 10 years I’m still healthy.”

The NBA regular season begins on October 20th.
