Agree to disagree. Preventing runs is the primary job of a pitcher. Of course some will benefit more or less from defense over the course of a season. Some also pitch in bigger parks and will see their FIP benefit.
Every measure can be nitpic'd. That said, nothing better captures a starter's job than earned runs allowed.
At the end of the day, scoring or preventing runs is all that actually matters towards winning or losing.
Terrible news, IYAM. Even if he comes back next weekend for a game, there's no possible way to spin this positively.
Even if the hamstring is 100 percent, not facing live pitching for 10 days is bad news.
Per MLB.com, Lewis to 10 day IL, Jordan Luplow recalled.
No possible way to spin this as anything but terrible news, even if he makes it back in 10 days.
I don't think the post season is the time to "find out" anything.
Ramp up Buxton for spring training. Find out then.
BTW, "unhealthy speculation" should have zero impact on anything. Certainly not something to base a playoff starting spot on. Holy cow.
WPA is pretty dubious in general, but has little to do with performance.
And if you want performance based measurements, you don't want fWAR for pitchers. It specifically measures what someone thinks should have happened rather than how many runs were allowed.
