Not trying to be a _____, but the guy has caught EVERY SINGLE INNING so far this season. And no, that is not the norm. I caught in high school and played an amateur baseball league (AABL) in college and catching all 9 innings on back to back days is tough. Much less 3 days in a row, and a 5 game week no less.
Point being, I think you can give the guy some slack. He's hitting over .300 and is the staple behind the plate. I think most of us just find it kinda funny that you or anyone would be thinking something is wrong with him. Most of the time people don't even notice all the work a catcher does because he blocks so many balls in the dirt. It's when they mess up or miss a ball that you notice.
