Him being off catcher almost certainly would have boosted his stats, there is a reason why he was the first catcher in like forever to win a batting title (not to mention multiple batting titles) Also this: Mauer has a JAWS right in line with the all time greats, he has a higher OPS+ then Berra, Bench, Carter, Pudge and Fish as well. Two more seasons like this one and he ends up close to Piazza in terms of WAR. It's not like the "hits" thing is an issue as well, most of the guys above him between 1900 and 2200 hits in their careers. Mauer should end up with somewhere between 2100-2300 depending on how much longer he plays. Again, up until this point Mauer has definitely been a hall of famer, a couple more years like this one, and then maybe one last "halftime player season or two" and he more than seals the deal (hits the 2000 hit milestone, 1000 BB milestone, 1000 R milestone, 1000 RBI milestone)
