For the past five years, Mark Johnson has slowly crept up the Cubs’ organizational ladder. After spending the past five seasons at the lower levels of the minors, he will be at AA Tennessee in 2016. Johnson has brought his expertise as a major league catcher to bear in developing a winning attitude on the field for his teams. Johnson’s best attributes as a manager are his no-nonsense style, his organization, and his handling of young pitchers and catchers. We tend to the think of the minor leagues as being all about the development of the players, but they’re where managers and coaches are developed, too.
