I mean, it's a systemic failure. The Cubs under Epstein have continued to hug certain guys too long (Schwarber, Almora, fucking Russell), and with regards to player development, until this year they continued to focus on low-velocity guys pitching to contact, praying they could develop the next Hendricks. (Arrested Development narrator: "They couldn't.")
The constant changes in the coaching staff have absolutely stunted Bryant, and I have a strong feeling that's why he's reverted to that long power swing that leaves a massive, gaping hole on the inside, especially low and inside. (I'm reminded of how the Bears fucked Jay Cutler by giving him like four offensive coordinators in five years or something like that.)
I agree that Maddon needs to go, as well as the coaching staff (well, I guess Tommy Hottovy can stay, considering he got Darvish un-fucked, and I've always liked Mark Loretta), but I don't really know who would be an ideal replacement. Girardi is known to want the job, but he and Epstein would get along like oil and water, and beyond that, hiring a red-ass jackwagon is just going to be Lou Piniella 2.0. On the other hand, they can't go with a mild-mannered retread like Scioscia or Ron Washington. With Bryant entering arb 3, Schwarber going into arb 2, Zobrist likely to retire, Strop, Cishek, Castellanos and Hamels going into free agency, the team is going to have a lot of complicated decisions to make.
