Nobody knows if Matt Harvey's shoulder is going to hold up to the point he again becomes a dominant No. 1. Nobody knows if Noah Syndergaard's lat injury is just a temporary setback or a precursor to more injuries after all that bulking up. Nobody knows if Zack Wheeler will ever maintain the necessary stamina to be a starter or if he needs to go to the bullpen. Nobody knows if Steven Matz can ever stay healthy for a full season and demonstrate consistent dominance instead of brief flashes. And nobody knows if Cespedes is forever going to have a hammy ready to pop.
