If you’re one of the NFL fans who thinks Taylor Swift is ruining football, Charles Barkley has a message for you: “You’re just a loser or a jackass!”

That was the NBA legend’s message Thursday, dunking on T.S. critics from the desk of his “King Charles” show on CNN … blasting fans who have come for Swift, accusing her of screwing up football.

“I’m gonna look right in that camera,” Barkley said, “If you’re screaming at T-Swift saying she ruined [football], you’re just a loser.”

Chuck continued … “You’re just a loser or a jackass. You can be A or B. One of the two.”

Legendary sportscaster Bob Costas — a guest of Barkley and Gayle King‘s — also spoke on the Traylor frenzy … and it’s clear he doesn’t believe the negativity will have an impact on the hundred-plus million fans who will watch Super Bowl LVIII.

“When it comes to the Super Bowl, where a lot of people who don’t watch football all year long, double the audience,” Costas said.

“Like 90 of the top 100 rated television shows in a given year are football games — almost all of them NFL games.”

The Swift Effect on the NFL isn’t a mirage … the Chiefs and the league have benefited from a reported $330+ million bump in “brand value” as a result of the high-profile relationship.
