This year’s Knockout Rounds have incorporated a new “Save” button for the judges to use – but the even better idea, incorporated for the first time this season, is to bring back former winners of The Voice as mentors for this new round. There’s no question this show is a superb showcase for the judges – but bringing back former winners is a way to remind everyone of the talent around which a singing competition series really is built. (Here’s Blake Shelton with his recent winning team member, Chloe Kohanski.) And new judge Kelly Clarkson, first winner of American Idol, embodies that idea perfectly as well.
