Chavez, Floyd and Osuna have all been excellent. I am not ready to write off Squints just yet, we'll have Loup back soon. The bullpen looks pretty good if Cecil can regain his form.
The season is very long, and the bullpen will improve, I'm almost sure. The only worrying guy for me is really just Storen. Hopefully he can get his velo back up but his drop is not comforting.
