The Astros have also had a ton of injuries, especially to the rotation and star batter, Y. Alvarez.
I do think you have to look beyond just the numbers of injuries and days missed, and many on this Yankee list are key players and some missed significant time, such as your ace being out all year, but I still think the significant injuries to the Sox are more influential than those to the Yanks. Yes, even two weeks missed by Judge, an 1.100+ batter, is likely worse than 4 weeks lost by Bregman, but Bregman missed more than 4 weeks. Our best hitter might have been Anthony, so it's hard to gauge how much missing him to injury is valued. Losing Mayer, Abreu for significant time and Casas (career .800 batter) for 5 months is pretty damn consequential. A little missed time by Narvaez, Ref and some other everyday players adds a little to the total numbers lost on O and D, but the big kaboom on the Sox injury front was with the rotation.
You may argue with how I rank our starting pitchers, but I'm looking at what I feel their pre-season rotation slot would have been, if they we totally healthy:
1. Crochet- no missed time (Cole was the opposite- missed the whole season)
2. Houck- last year's #1- missed 23 GS
3. Crawford- last year's IP leader- missed 32 GS
4. Giolito- missed 4 starts
5. Buehler- missed 0 GS
6. Bello- missed 3 GS
7. Sandoval- missed the whole season.
8. Fitts- 10 GS- missed about last 1-2 months.
9. Dobbins- 11 GS- missed over half the season.
10. Criswell- 1 GS- missed the last month.
We ended up using Newcomb, D May, some pen starts and then a couple rookies not even considered depth back in March.
The pen has been pretty healthy, but Hendriks was considered in the running for the closer or top set-up man, He missed the whole season. Slaten was widely viewed as our top 4 RP'er and missed a couple months. Other lesser arms missed some time.
Your Yankee list is significant, too. I'm sure you could justify the value lost as being close to the Sox, but I'm not sure it would top ours, and since ours was concentrated in the rotation, which I consider most important to a team's success, I'm probably biased on that point, too.
