'A spectacle to behold': Here's what J.J. Watt thought of Taylor Swift's The Eras Tour concert

Apparently, J.J. Watt is a Swiftie. He even has merch to prove it.

The Wisconsin native and three-time NFL defensive player of the year attended Taylor Swift's The Eras Tour show on Saturday with his wife, professional soccer player Kealia Ohai, and her friends at State Farm Stadium in Glendale, Arizona. On Sunday, he posted a video on Twitter, sharing what he thought about it.

In one word? "Unbelievable."

"You can tell when somebody does something at the top of their game and is trying to do the right way for their fans," Watt said in the video. "And this is done the right way for the people paying money to come and see her."

He praised everything from the production and set design to the video boards and sound quality. And of course, the queen herself.

Swift performed 44 songs over the course of the 3-hour and 15-minute concert. And she sang, danced and entertained "the entire time." While Swift didn't even seem tired, Watt said, he was just from watching.

The fans — there were about 70,000 in attendance — were "hanging on every single word" and move Swift was making, and were singing, screaming, dancing, and jumping right along with her, Watt said in the video.

"It was a spectacle to behold," Watt said. "It really was."

A USA Today review called the production "as ambitious as a Broadway musical." There are moving set pieces, squads of dancers and backup singers, a quick-change costume parade, confetti, pyro, synchronized blinking wristbands, a curved video screen and more.

"Hat's off to everybody involved, the production, Taylor, the whole crew, all the fans," Watt said in the video. "It was impressive to witness."

The Eras Tour has more than 50 dates across the country through August.
