Created by Charlie Grandy (“The Office,” “The Mindy Project”) and Mindy Kaling (“The Office,” “The Mindy Project”), “Champions” is a half-hour, single-camera comedy that centers on Vince (Anders Holm, “The Mindy Project,” “Workaholics”), a washed-up high school baseball star who reluctantly gave up his dreams to take over the family gym in Brooklyn.
