Winning the 1986 World Series should have earned Davey Johnson a lifetime gig with the Mets and legend status in New York. Instead, he got three more seasons before getting canned 42 games into the '90 campaign (the team was in second place). The next three full years Johnson served as an MLB manager, he led his team to the playoffs, while the Mets suffered through the Bud Harrelson, Mike Cubbage (!), Jeff Torborg, and Dallas Green errors, er, eras. Not for nothing, Johnson is still the Mets all-time winningest manager.
