Taylor Swift is a Travis Kelce fan and suddenly, so is everyone else as NFL player's jersey sales skyrocket

Taylor Swift's trip to watch the Kansas City's Travis Kelce play football on Sunday didn't just have the internet talking nonstop. Following the 12-time Grammy Award winner's appearance at Arrowhead Stadium, jersey sales for the All-Pro tight end seemingly skyrocketed.
