There will be better catchers out there than a 33-year-old Manny piña. With multiple suitors and who'll cost way more and no guarantee to get them. If you sign them, well then you can not sign Pina back or keep him as backup, trade others, whatever you want. In NBA terms, think of it as not giving up an asset for nothing. There sure is a lot of recency bias when it comes to Pina. The guy is a solid defensive catcher, and was very good offensively in 2017, and still pretty decent last year. Yeah, he hasn't been great in very sporadic playing time this year, but as a reserve catcher, you can do a heck of a lot worse than Manny Pina.
