Taylor Swift has blown away countless fans over the course of her record-breaking Eras Tour, including all-time great NFL edge rusher J.J. Watt.

On Wednesday, Watt joined unapologetic “Swiftie” Pat McAfee for an appearance on “The Pat McAfee Show.”

McAfee attended one of Swift’s Eras Tour performances at Indianapolis’ Lucas Oil Stadium this past weekend. Watt went to the very first show when the tour kicked off on Mar. 17, 2023 in Glendale, Arizona.

Both former NFL players were absolutely floored by Swift’s performance.

“Unbelievable. Unbelievable. I mean, shocking,” Watt said.

As an elite athlete, Watt went on to applaud Swift’s “stunning” stamina.

“I am truly impressed by the physical stamina and ability of it,” Watt added. “I don’t think people give that anywhere near enough credit… I don’t think they understand how difficult that has to be to get up there for that long every night.”

Coming from Watt, this means a lot. The three-time NFL Defensive Player of the Year is one of the best conditioned athletes the league has ever seen.

McAfee shared a similar sentiment.

“I didn’t know you could be that electric for that long,” he said. “… Stamina. We’re talking stamina.”

The Eras Tour has shattered the record for the highest-grossing tour of all time. Swift has nine more shows before the historic tour comes to an end: six in Toronto and three in Vancouver.
