Tom Kelly was never a good player, had a personality that is best described as good behind the scenes and an overall record 202 games under .500 yet he is well liked by the fan base. I guess that's what 2 WS championships will do for ya.
Ron Gardenhire was an irascible, cheap beer drinking scrub utility infielder from Oklahoma with a career record 80 games over .500. His teams made the playoffs many times, but had no success there. He was also well liked by the fan base.
Rocco Baldelli is a totally different animal. A top prospect from the east coast, the start to his major league career showed much promise. The guy could really play, but a rare condition led to many injuries, ending his career prematurely. He stayed in baseball learning ins and outs at one of the more forward thinking organizations in baseball. He is a more sophisticated type, articulate and married to an artist. In 3 short years he has 2 division titles and is already 41 games over .500 in spite of a down year last year. The guy is not universally liked by the fan base however. Even after wins people will go out of their way to say how the Twins won in spite of him. I guess we prefer everyman types, over achievers who drink cheap beer and kick dirt at umpires.
