Gary Carter was originally an outfielder who was converted to catcher because the Montreal Expos had a stable of good players at that position. Speaking of the Expos, they had a handful of truly great players come up through their system in the 1970s and early 1980s. In addition to Carter, there was Andre Dawson and Tim Raines. All three are in the Hall of Fame, and they played together in Montreal from 1979-1984. It's amazing that the Expos never got to a World Series during that era with such great players on their roster.
