It doesn't sound like he won't catch at all, from the quote. I would imagine he'll catch a bit but also DH, get some reps at 1B, maybe even 3B.
I honestly think it's a good idea. We see catchers increasingly getting Tommy John. We've seen lots of catchers have careers derailed or cut short by concussion issues, chronic leg issues, inexplicable drop-offs in production that may be caused by total wear and tear. Some time off of the position might benefit him long term.
