But my point is the elite guys who are spammed game after game are at least as valuable/talented as the starting pitchers (the mediocre ones), the others are just regular relievers who are there simply for matchups and they sometimes pitch in regular days following the starter anyways. I don't think the league will ever value a one batter/inning guy over a similarly talented multi-inning one, and certainly not if they can go for 5+ innings.
In the Oakland game, Hendriks was supposed to go 2 innings followed by Trivino for probably 2-3 more if he was effective, and after that it's basically as if a starter had gone the same distance. Those two combined on a regular day are definitely at least as talented as Mike Fiers, and individually they probably are as well, the latter holds some value in a long regular season but not a short and intense postseason.
I'd argue the league is moving away from putting pitchers in less favourable matchups, such as making a non-elite starter go through the lineup a third+ time, or starting them against the top part of the lineup. And I think this is an awesome strategy, and in no way is favouring your random fireballers who don't know where the ball is going or LOOGYs over capable starting pitcher. None of these scrap heaps guys are sticking around for very long, and they won't be replacing legitimate effective multi-inning guys.
I don't think any team is spamming guys who throw 99 for the sake of it for only an inning each. Guys like Josh James and Woodruff are only in the bullpen temporarily because they're not polished enough (arguably) to make high leverage postseason starts yet and can provide incredible value in short spurts. You'll likely see them in the rotation next year unless they become 3-4 inning elite guys which the analytics might value more.
