I mean maybe?
Padres could maybe move on from Derek Norris, but, he's heading towards his second arbitration and already making 3M(and is a former All Star so you'd be paying for bounce back most likely)
Rockies could maybe move Nick Hundley, but, he's a worse pitch framer then Thole this season.
Jeff Mathis could come back from Miami, might be the best of the best available.
Dinner Plate? Ugh no.
AJ Piersynkski? Ugh no.
I really don't see a lot of names being out there that make sense as a back up catcher. And Thole was on the playoff roster last season, so it's already happened, you don't need to imagine it.
