Sportsmanship involves respecting opponents, teammates, officials, and fair play. It means abiding by the rules without cheating. Mike Tomlin demonstrated poor sportsmanship by interfering with a play for the opposing team. In contrast, Red Sox owner Tom Yawkey showed good sportsmanship by dedicating himself to helping others through founding a charity. Athletes like the McCourty twins exemplify good sportsmanship by giving back to their community through initiatives to help others and teach youth sports.
