60 WAR seems to be the bar now (at least that's what it's become for hitters), and DeGrom (by FanGraphs' math, at least) is still below 50. So he's not a lock, but two more elite seasons would put him in the running.
While I'm looking at FanGraphs, it's worth pointing out that his fastball has been faster than his 2018 level every year since. And with the exception of the 2021 season, when he blew out his arm and took the team's playoff chances with him, he hasn't been as good. And of course, he hasn't been anywhere near as healthy. There is a moral in there that a whole lot of baseball people are ignoring.
