I'm a bit late here on this, but I really like the Luzardo trade. There are obviously risks given Luzardo's health and given Caba's defense and on base skills, he has a really high ceiling if he can add some strength.
But that's a massive if on Caba and if he's healthy, Luzardo is a legit #2 or #3 starter.
And given that the Phils clearly decided that they weren't going to be able to upgrade the lineup like they had hope, I like they pivoted to a different strategy.
I also love the idea of a six-man rotation once Painter is ready to lighten the innings load of all of the starters so that they hopefully have more in the tank come playoff time.
