How productive is complaining about a severely injured pitcher who would never have been here without the injury? If the irony and futility of that exercise is not plainly obvious, then I can't help you. Robe can't fix his arm. He needs to focus in other areas. Did anybody consider the likelihood of recovering from two surgeries and only missing a season was hopeful at best?
Say somebody gave you a car that no longer was driveable, because it was no longer drivable. For two years you complain about your car that is not useable, that you would never have if it was useable. That makes a lot of sense.
I get it. The pitching is bad, but crying for two years over Gunner has not helped our ERA, has it? Exactly when will the whining help us win? I guess its easier to dwell on what you can't control than all the decisions that got us here in the first place.
