Not to my understanding - it's supposed to isolate the impact of one player independent of everything else, I believe.
Snell and Verlander were pretty close last year. Snell had more "luck" as his FIP was over a whole run higher than his era.
The bolded part does not appear to be accurate. JV gave up a lower percentage of hard hit balls. JV gave up weaker quality of contact (i.e. xwOBA) based on exit velocity and launch angle than Snell. It was more about placement relative to fences and defenders. The biggest area that stands out is on balls hit between 340 and 400 feet (gray area of sometimes a homer, sometimes not); JV was over twice as likely to give up a homer than Snell (21 homers out 60 batted balls for JV in 214 innings [35%] vs 7 homers out of 43 batted balls in 180 innings for Snell [16%]). Snell appears to only have given up flies balls to Kevin Kiermaier in 2018 while JV more likely had balls hit to right or left field.
Just to demonstrate the difference between Minnesotans and Houstonians, they just showed fans entering Target Field and damn near all of them were in shorts and short sleeves. It’s 43 and raining. Pure savages.
