Bench was a dangerous hitter and a Gold Glove catcher when he was 21 years old, and arguably the best player in baseball when he was 22. He won two Most Valuable Player awards by the age of 24. He led the National League in RBI’s for the third time when he was 26 years old, the same year he won his seventh Gold Glove. His fame transcended baseball. He was a handsome Oklahoma boy with broad shoulders and long sideburns and a country western singing voice.
He was a middling defensive catcher, but Posada did other things, like draw walks and hit for power with his pee-stained hands. He was overshadowed by famous teammates, which is a recipe for Hall of Fame injustice.
Four catchers have had at least ten seasons with 20 or more homers: Johnny Bench and Mike Piazza (eleven each), Yogi Berra, and McCann. Pretty good company. McCann was the only one in that group to never drive in 100 runs. However, his eight 70-RBI seasons were exceeded by only seven catchers in history.
