No, but we know healthy starting pitchers in there early 30's typically get more than 2 years, there's certain free agency universal truths we can count on.
And WAR has been a very good predictor of free agency pay days with very few caveats (guys taking less AAV for more years and vis versa). Take almost ANY pitcher who has signed a multi year deal and divide their AAV by their average WAR and you're typiucally getting around $7-8 per WAR. Pivetta is about a 2-2.5 WAR pitcher. Depending on length of contract, he's getting around $16 million a year give or take.
With guys getting 10 years now, thinking he could get 4 is beyond absurdly reasonable. 2 years is an insult.
Reality is, if you don't want to give Pivetta at least $50 million plus just say you don't want to resign him, which is fine.....I don't. I'd rather look for ways to UPGRADE this rotation.
