Some interesting takes on Mauer, and my net takeaway is that there are a surprising number of reasons (and of varying legitimacy) for disliking Mauer. Will throw one more into the mix. In a discussion of the hand-wringing over Mike Piazza's defensive issues in his prime, Bill James posited that there's a very strong tendency for bad franchises to blame their struggles on their best player. Whether it makes them 'bad fans' or not aside, it seems to me like there's a similar tendency among fans. Nowhere was it more clearly on display than in a thread somewhere several years ago debating the relative value of Joe Mauer and, I swear I'm not making this up, Nick Punto. While on some basic subatomic level Mauer and Punto had the same exact job, to help the Twins win baseball games, every fan was free to make up any job description for them they wished. And there was a fair-sized contingent whose job descriptions went like this: Punto - Field multiple positions, use up bushels of outs at the plate, and turn his uniform brown (from the outside, not the inside). Mauer - Carry the team to a championship. Defined by those terms, Mauer was virtually guaranteed of "failure" due to odds alone, with only the details of how he failed (too little power, not 'aggresive' enough, lack of leadership, etc.) being argued amongst them. Meanwhile Punto was absolutely assured of "success" as long as his defense remained passable. Although that school of thought utterly baffles me the way breaking stuff baffled Greg Gagne, like I said, everyone is free to define a player's role and their expectations however they want. That said, the people who define Mauer's career in the terms above seem to me to have been missing some of the enjoyment of what was until the concussion almost certainly a Hall of Fame career.
