They won't until they do. Every FA looks good, until they don't. I still remember the rejoicing in Colorado over signed Bryant, while I was telling them, before he even stepped on the field, that they should trade him to the RS, along with $51M. That's how overpaid he was, even on the first day.
Bregman is better than that, but the number I came up with to Kimmi was $125M/5 based on his projected WAR and decline.
