Smyly looks for real, one bad pitch at the worst possible time, then he recovered and gave them 3 good innings and could have gone deeper. Nola, Smyly, Vargas, Arrieta, Velasquez isn't ideal, but if they had a deep bullpen they could win 90 games with that group, with the current bullpen, winning 85 will be an achievement - Neris, Pivetta and pray. Suarez and Alvarez are passable, but Morin, Parker, Nicasio, Eflin are long relievers at best.
They need the young kids to step up the next couple years, Harper can hit better but it may take a year or two for him to accept that swinging for the fences is counterproductive, Rhys is about as good as he's going to be, Realmuto is going to end up above .800 OPS, but Hernandez, Segura, Bruce/Dickerson/Cutch are what they are.
So any real improvement has to come from Kingery, Quinn, Bohm, Haseley, Moniak, Stott the next 2-3 years.
