(emphasis added) The counterpoint here is that if the only proof is that 'it makes sense that this was the reason', it sets a pretty broad precedent that could be used in cases that are far less obvious. Maikel Franco filed a grievance too, and he was thought to be a rich man's Josh Vitters until last June or so. People wailed about the Pirates killing their chances by leaving Polanco down for Super 2 reasons in 2014, then when he did come up he was barely replacement level. I wouldn't be stunned if the Cubs lost the grievance, but my feelings are similar to the Maddon tampering stuff. Unless there's some smoking gun where an email said 'Bryant won't start with the team because service time' or something like that, I don't think there's a high chance that Bryant/Boras/Union wins. But winning this specific grievance likely isn't the point anyway. I'd be floored if the Cubs lost the grievance as it would require something pretty stupid to have been said/written and captured in a form that can be used in the hearing. The article quoted by kyle is written by a guy (a labor union lawyer, btw, so not entirely unbiased in a union v company dispute) arguing that "it's not illegal, it's legal" which is far different from "the cubs should/will lose." The league has a CBA. They all agreed to the service time rules. Do they also have to act in "good faith?" Yes, but that's a really ambiguous requirement and this is not kindergarten. If there's any defensible reason for the Cubs bringing Bryant up when they did, then they win. It would be madness to have team decisions subject to some guy (with the benefit of hindsight in the form of 5 months of stats) to evaluate the circumstances, find that the Cubs had a defensible position, but that he'd come to a different conclusion, so the Cubs lose.
