To me, Ohtani, Urias, Nola and Severino are the only ones that look like upgrades to what the currently have, and three of those guys have injury histories that make Rodon's history look like a hangnail.
I mean, they're coming away from this offseason with their tails between their legs, so maybe they do change their approach next year. Ownership is going to get throttled in the media and fandom for carrying an embarrassingly low payroll this year, they might tell the front office to get something done, or they're done.
