Not even close to enough for DeGrom.
He is going to provide a contender a huge upgrade this year. He is probably going to project to 2-3 wins the rest of the way, at a cost of ~$3M. Elite SPs carry a huge premium for contenders, so I'd estimate his 2018 surplus value alone to be roughly $60M.
He is then under control for another 2 seasons, and will make about $25M-$30M via arbitration. He will easily be projected for ~10 wins over those 2 season, which represents another $70M in surplus value.
That's a total of $130M in surplus value to get DeGrom.
Propects are valued roughly as:
FV 75 = $175M
FV 70 = $107M
FV 65 = $70M
FV 60 = $60M
FV 55 = $38M
FV 50 = $20M
FV 45 = $11M
FV 40 = $5M
The Braves simply don't have a headliner worthy of DeGrom (other than Acuna and Albies), and the Mets would be foolish to take a handful of 55s and 50s worth $20M-$40M each when they can get 60 as the centerpiece...as these TOR guys with control always net in the return package.
How much surplus value do you think Newk has?
