Galvis and Rupp will be worth more this winter than they were last winter or in July, the combination of improvement and continued production raised their value.
Same with Hernandez, teams won't worry that last year was a fluke.
The other pitchers don't impact Nola, the defense and bullpen does. And Eickhoff, Lively and Leiter have the potential to be innings eaters (Eickhoff is one, even with his arm problems, loss of velocity, this season).
Yes, you want to eventually upgrade, but right now I'd be happy with any young starter who can consistently give you quality starts (6 IP, 3 or less runs).
Velasquez, Eflin and Pivetta have better FBs, but right now they're not ML pitchers.
Crawford has had two good months after almost a full year of mediocrity in AAA ball. He's neither ready or not ready, he's sorta in limbo, not playing well enough to make promotion a slam dunk, but well enough that you wouldn't expect him to fall flat on his face. So it doesn't matter if he starts in 2018 or waits until July.
Patience merely means making the best moves for now and the future, and not making moves just to be seen doing something, anything.
Once teams know Klentak doesn't feel the need to dump anyone, they'll bring him real offers.
