I maintain faith that in a reasonable sample size, Thole is considerably better than JPA. Now, that's not a ringing endorsement or anything, but Thole has put up decent numbers in the majors in the past, whereas JPA never has...

The only stat that JPA has ever been above the "league average" line has been SLG, and not by a lot.
Also, Thole's BB% is crazy at the moment... but again, SSS!
