Does Corbin Carroll count? He got almost as much time as Gunnar. Does Francisco Alvarez count more because he only got like a week in MLB? Do Brett Baty and Triston Casas count because they're only top 25ish instead of top 10?
The rules are the rules and make it easy, I think there's lots of similarly situated guys so it's no big deal. Seems silly to arbitrarily call some people non-prospects, unless you want to use zero MLB time whatsoever I guess. And then I guess for the others, zero time in the top league in a country.
The recently graduated prospects I get why rookie status is as good of a choice for a firm rule about eligibility for such lists as any. I think that's a bit lenient if what we're really looking for is farm system prospects, but would be hard-pressed to come up with a better rule that has widespread application. The complete opposite scale metric would be ineligible once they see any MLB time. Could be better, could be worse, and very difficult to think of a good benchmark in the gray area in between. More work, but would be interesting to see the same list but with anyone with MLB service excluded and the next X guys below 100 who would qualify moved up.
The veteran international FAs don't really make any sense to be included, though. These guys aren't the farm system, they are MLB players. I think they should exclude players who signed without being beholden to the International FA restrictions, even if they have no service time yet.
