I clearly remember in 2019 that a bunch of us thought the return of Leon would save us from Restgate. It didn't happen, the pitching got no better at all.
And it was goodbye Sandy.
I don't know that he isn't worth it. It's not easy to evaluate a catcher's defensive value. It seems pretty clear to me that CERA has no impact at all on how the team evaluates him.
IMHO Sale and Eovaldi were never the issue with keeping Betts. Their deals weren't signed until they gave up on Betts.
The more I think of it, the more I think Henry and Werner were really pissed about Mookie's stance (the 420 million counter offer plus earlier extension rejections) and closed the books on him.
It was a small sample but a decent sample. 2020 of course was a weird year all around. His pro-rated salary was a little over 6 million.
Bottom line, he's had one bad season, 2019, on this contract.
