Sure, Fangraphs uses WAR to cook up a fancy stat on what production is worth on the open market. It's high. I can check for you the numbers on Flaherty and Greinke. It's an interesting way to look at the players and their production, and they're all on the same scale, even if it's a touch inflated from what we see in the open marketplace. You'll get that sense when we compare FanGraphs "dollar" value to the actual salary:
Jack Flaherty, made $562,100, pitched like a $38m player.
Zack Greinke made $31.5m, pitched like $43.3m
Justin Verlander made $28m, pitched like $50.9m
Gerrit Cole made $13.5m, pitched like $59.4m
Go over to FanGraphs and float around for a bit on the individual pitcher pages and player pages and you'll get a sense of the dollar value they assign, and, yes, it does use WAR as the basis for the estimate.
