The Cubs basically haven't been on the cutting-edge of anything the last few years and that is pretty frustrating and is catching up with us, similar to how we were behind the developing velo race for a couple years before it seemed like we made inroads, only to fall into the middle of the pack. We thought we had guys in charge that would be ahead of the game on each innovation but it seems they are lacking on several fronts. IMO improving control and command is way behind in our org, as well as getting hitters to pull fly balls and keep the ball off the ground. I don't know how other teams are doing it so well, but they are.
Side note: seeing Breslow go entirely against the grain and go away from fastballs and pull out another Arrieta in Houck is pretty annoying too.
