I agree with your point, but how many SP'ers were on the Sox for all 4 years of the sample we are looking at?
BTW, ERod had a 7.1 bWAR from 2019-2022 to Nate's 7.0 bWAR.
ERod missed 2020, but thats till counts. He was with DET in 2022, otherwise, he'd have had a higher bWAR than Nate. (Note: in just 2 seasons: 2019 and 2021, he had a higher fWAR than nate's 4 seasons.)
Sale was here for the 4 years, but missed time.
All the others have 1-2 year sample sizes in that 4 year stretch, so the statement, "highest WAR" in 4 years rings a little hollow, or needs some serious context, IMO.
fWAR 2019-2022
7.6 ERod
7.4 Nate
6.9 Sale +Price or 6.3 Pivetta + Price
Cobble together some 1 year guys:
2.3 Price in '19
0.4 Perez in '20
1.8 Houck in '21
1.8 Hill in '22
6.3 Total, which is pretty close to nate's total.
Using bWAR
2.1 Sale in '19
1.3 Houck in '20 (just 3 GS)
2.5 Pivetta '21
3.3 Wacha in '22
9.2 total to Nate's 7.0 bWAR
