I don't know nearly enough about organizational structure, priorities, etc, but honestly at this point it's mainly the complete lack of relief arms coming through the system that all other teams seem to churn through with ease. Palencia was....fine last year. He was also 25 years old. And there doesn't really seem to be anyone anywhere close to being one of those guys either. Guys like Palencia, Azlolay should be coming through all the time, not once every couple years. It's a much bigger problem and solution than to try and write out in a couple paragraphs, but ultimately the results just haven't been close to acceptable.
Pitchers break, they hit a wall, I get it. But this pitching staff is not one Cade Horton and one half of Ben Brown away from being even average. I liked the Zef pickup because it seemed like they were finally trying to find some guy with nasty stuff that would be around for seemingly forever (see: Abner Uribe, Ashby, Megill), and I admittedly bought in on the 'woah guys, look at these 16 innings'. But even that's been ugly so far. It's incredibly difficult and complex in a way that like....Bregman vs Schwarber isn't. But they're very clearly worse at it than almost every other legitimate major league team.
