Last week, in our Collector’s Case Study on Adley Rutschman, our career projections showed that he could end up with career stats close to Buster Posey’s.
All week, we’ve been thinking about that comp. We pointed out in the case study that a major difference between Posey and Rutschman is that Posey played his entire career in San Francisco. After this year’s trade deadline, Adley lost the chance to do that in Baltimore.
These days, staying with one team for a whole career is a rarity. But it’s still a narrative that can really move card prices. We want to know by how much.
So today we’re going to try and put a number on it.
We’re pulling PSA 10 rookie cards from pairs of players in each of the three major sports, matched on stats and accolades as closely as humanly possible.
We’re trying to keep this in a vacuum, so we’re picking pairings that rule out the other things that drive card values. Differing levels of popularity. Significantly more rings or MVPs. Different eras of Wax. Stuff like that.
If this works, we’ll walk away with a number we can use in future case studies.
Let’s rip in.
