It's a tough situation to handle, we can all agree on that.
On paper is Vlad "worth" $420M or more? Based on his age and projections he might be by a $/WAR calculation. The market seems to say he is if you use the Soto contract as a measuring stick. However, by a ton of other precedents the market has said for a long time that he shouldn't be worth that much.
Regardless, how many players like this are ever available, at all? 25/26 year olds with a 5+ WAR projection. He is young enough that you could give him a 13 year deal, suck for two years right away, and still have him for two cycles of competition in the remaining 11 years.
How much do you just begrudgingly overpay to lock up the rare asset?
