Except when it's not? Like when it says Radke/Schrezer were comparable?
In terms of runs allowed, when accounting for context, they were comparable.
In terms of runs allowed, based on the very narrow definition that BR WAR constrains it to, then perhaps. But it - really - doesn't tell us that Scherzer is a better pitcher than Radke. And we can't reliably assume that if the pitchers were switched, that they would perform relatively the same in each of the other's era/team.
That's all that WAR measures. In terms of runs allowed, accounting for context, how good was the pitcher? It doesn't measure how the
would perform, it only measures how he
did perform.
We can reliably infer that a 2016 NL pitcher would give up more runs in 2000 AL than he did in 2016. And vice versa, if 28 year old Pedro Martinez popped up in 2016 instead of 2000, he probably would have been even more dominating.
