In the end, it won't surprise me in the least if we are unable to extend any of the 3. If that is the case, and the organization knows this now, maybe it's time to trade Burnes and Adames now, and Woody after next season. Burnes value may never be higher, he is the one I would look to trade immediately to maximize value.
Once Correa is all straightened out, and we know where he is going, I'd be making calls to the teams that were not able to get their high priced SS this off season.
