There really are times I wonder about Maddon. He sticks with what works too long after it stops working. He definitely leaves Arrieta, Lester or Lackey in too long at times, even when they're clearly gassed. But then he will take an on-fire Hendricks out in the fifth because they're down one run.
I said it when he was hired: Maddon, beyond his "quirky" personality and making players dress up in goofy outfits or whatever, just likes to pull levers and push buttons, and much of his reputation as a great manager comes from breaking out shifts that hadn't been used since the '50s. He has a lot of knocks against him, particularly bullpen management, which is a rather dangerous combination when he's working with Epstein, who has never in his career built a genuinely good bullpen.
He's definitely not a Don Baylor or Jim Riggleman or some dumpster-dive like that, but I don't think he deserves to be lionized. Arrieta, in particular, should have gotten a lot more rest than he did at the tail-end of 2015, and anyone with half a brain could see that Hammel was toast at the start of August.
