When it comes to "creative" trades, I am all aboard the idea of taking on the full boat on Grienke to get Goldschmidt with him, and to not pay much for it. That still leaves you room for another superstar.
It would have to be something like $10 million per year more than the best long term offer they got to make it worth while, especially since both are sure to get opt outs anyway.
He has one year of control left. Whoever signs him, he will be available in another year by all odds anyway, as it isn't like anyone is giving him a long term deal anyway.
I don't think that there is any question that failing in NYC is worse than failing anywhere else, except maybe Boston. The Chicago press is a lot more in league with the teams for some reason. Fans feed off of that to some extent.
Comparable contracts are quite literally how other people decide what to ask for in their own negotiations. There is no better point than a player of the same age, position, and offensive set to project someone's future deals.
I am sure that is it.
Or, this is easy to find information that a ton of institutions ran stories about during the Kananaugh hearings and sighted typical false reporting rates of 4 to 8%.
