Hall of Famer Brett Favre thinks Colin Kaepernick could one day be considered a "hero" to football in a similar way as the late Pat Tillman.
During an interview with TMZ Sports, Favre was asked if Kaepernick compares to sports figures like Jackie Robinson and Muhammad Ali and if he'll end up in the Hall of Fame for his work as an athlete and activist.
"It's not easy for a guy his age, black or white, Hispanic, whatever, to stop something that you've always dreamed of doing and put it on hold–maybe forever–for something that you believe in," Favre said.
