With no control over Griffin after this year, it's really down to extend him now for more money than he's ever seen, deal him at the deadline if we are out of WC, or push at the deadline if we are in contention for the WC.
I will guess Toboni will argue against the latter if it could adversely impact the long term build out. He's from the Red Sox system, and they've pursued half-hearted deadline moves since 2019. I'm sure he doesn't want to be on the wrong end of the equivalent of Mike Soroka for Christian Franklin and Ronny Cruz.
I could see making Griffin an offer for his age 31-33 seasons as birn g attractive to him after kicking around for a dozen years. He runs the Fedde risk if he doesn't. There were only 5 contracts this past winter given out that were longer than 3 years (Cease, Suarez, Valdez, King, and Ponce). See if you can guarantee him something in the $15-18 million range for the next couple of seasons with an option for a third. Of course, this also depends on ownership being willing to to commit Trevor Williams+ type money again.
Realistically, he's being dealt at the deadline if he shows anything over the next 3 months.
