Wow…what a great picture.
The first thought that comes to mind is “who was the better manager?”, but I don’t think the answer really even matters. Tom Kelly brought a “fundamentals” approach to MN, and Gardy has simply continued that tradition. That consistency has allowed the Twins to build such a fine organization over the past two decades.
I found another pic that does show the main difference between Gardy and TK:
TK was almost always a calming presence, while Gardy brings a bit more “fire & brimstone” to the dugout. Other than that, though, both managerial philosophies were the same: learn the fundamentals, respect the game, hustle and have fun.
