Confidence knowing I'll have 200 IP at a middle of the rotation type effectiveness. All his injuries were flukes. Guy is a 2 WAR pitcher right now as a floor based on what I'm seeing. I'm also not sure why you think his range is 4-4.5 unless you think he degrades this offseason.
In terms of hard contact this is a listing of pitchers that have worse barrels per PA than Bumgarner:
Cole
Scherzer
Berrios
Taillon
Ian Anderson
He scores even better when you look at barrels per contact.
Can you elaborate on what you mean by 'attendant health concerns'?
He isn't even going to throw 200 innings this year. Probably end up around 160 innings pitched. And he has thrown 200 innings exactly once since 2016. But somehow he's going to do that over the next 3 years with a declining skill set and getting older..... Right......
