Compares his interesting combination of power and low OBP historically and with other catchers. Don't quite agree with his conclusion that JPA is ikely average defensively. Also, interesting related note: Fangraphs has just implemented passed pitches into their catcher defence, and JPA last year was worth -6 runs, which is one of the worst performances for the 2008-2011 time period it can be measured. THat moved his defensive runs from -5 to -11, and his overall WAR from 1.5 to 0.9.
