If we didn't already have an entire staff with injury concerns, I would be all over DeGrom. But that's too much risk that leaves you without much flexibility in the event he gets hurt or sucks.
Based off the deals and rumors so far, AA seems unwilling to tie up a lot of extra money into future seasons. I assume he doesn't want to run into another scenario like last season. I would assume whatever SP we are looking at won't be a FA SP or trade target that will require 5 years or more and 25+ million per year.
