I would still bring in another starting pitcher through free agency.
You see Gray, Mahle, Ryan, Maeda, Ober, Paddack, Winder, Varland, SWR and Balazovic
I see good, injured, decent, old & injured, injured and inexperienced, injured, injured and inexperienced, rookie, rookie and ineffective.
Almost everyone is either past their prime, coming into their prime or coming off an injury. They had nearly the same mix of pitchers this season and still gave 300 innings to Bundy, Archer and Smeltzer. It would be great to add someone like Kyle Gibson, Jameson Taillon or Noah Syndergaard to that group. They can move Maeda and/or Winder to the bullpen if needed to fit everyone on the roster.
