Those aren't the best things to look at. Mauer's OPS is very impressive. Without adjusting for ballparks, it's above guys like Dunn, Tulu, Cano, Beltran, HanRam, Rolen, Willingham and Morneau. When you take ballparks into account, his 135 OPS+ is the same as Ryan Howard, Josh Hamilton, David Wright and Todd Helton and above guys like Teixeira and Kemp. That's just his bat. No extra credit for doing it as a catcher.
