I hear you, but I think WAR (a counting stat) might be exaggerating the difference, especially looking forward. Here they are by a rate stat, FIP- (FIP adjusted for park and league), since 2014 (the start of deGrom's career): deGrom: 72, 70, 82, 82, 49, 72 Sale: 66, 66, 81, 56, 48, 71 Advantage Sale, but the "stability" you mention is basically exchanging one extra excellent 56 FIP- season for one still good 82 FIP- season out of those 6. Otherwise, they each have one excellent season, one still good season, and Sale is basically 66-71 and deGrom 70-72 over the remaining 3. (Sale's two earlier 76 FIP- seasons as a starter would further suggest he's closer to deGrom than you might think.) This surprised me, as before I researched this I would have assumed the gap would be larger than that. And in terms of workload, Sale had an advantage in starting his career earlier and "earning" a larger workload earlier. deGrom actually has more IP and IP/GS over the last 3 years so I suspect that part might be equalized going forward. (Add to it that Sale already had a shoulder scare late last season.) I mean, I agree that I'd prefer Sale if they are both available to me at equal cost, but they are close enough from my vantage point that I'm not sure I could ever turn down deGrom just because he's "not Sale" and Sale isn't actually available to me.
