Torre is a pretty good example of this case (903 G@C, another 1100 mostly at 1B and 3B). He got 22% of the vote in his final year on the ballot, and didn't crack 15% before that. Mauer just passed Torre, and has played 920 G@C so far. If he never played another game at catcher, I could see him ending up with very similar WAR and JAWS, probably a bit higher. Torre was arguably slighted by the voters somewhat; he is in the Hall of Stats. But moving away from catcher definitely seems to have hurt his case. Right now, I think Mauer is still a borderline case. The traditional voters will definitely like his batting titles and MVP, though 6 ASGs is quite low for any position and his counting stats, especially HR, are well below average. The statistically inclined voters will see his value, though I'm not sure he's accumulated enough career value yet. If he plays another 2-3 years mostly at catcher I think he'll be a lock. Or if he plays another 5-6 mostly not at catcher, he'll probably still be a lock. Either way, as a squeaky clean guy who's never had any controversy whatsoever with the media, I think he'll outperform many contemporaries with comparable advanced stats in the vote.
