2 anecdotes prove what exactly? That nothing is certain? We already know that. Projections are about probabilities, not certainties. No projection model is making the bet that Cabrera is throwing more innings, has a lower ERA, or a higher WAR next year than Cease.
A serious owner would give his FO the resources to get someone who is likely to both make 2 strong starts a series and be on the field to do it.
Anyways, Jed has done his duty, so for that I'm grateful. Go Cubs.
