For youth teams you gotta dig deeper, as the JFF communications is worst than the CSA, and the Gleaner will put it in their reports in small parts that your algorithm can't easily find. I know because I occasionally visit the reggaeboyz forum to find out the latest happenings of the team. So go there and you'll find additional information if you want.
It's how I know Demarai Gray has finally got his paperwork sorted.
I know they did an ID camp for the U20, and U17s...it how they got players from Atlanta United, Toronto FC, and Inter Miami academies. They've done this also with the ladies, as majority of their team is Jamaican "diasporans". But again, my main point is that it shouldn't be comparable....but it is.
Jamaica for a fact does more local camps than we do. I guess from before it didn't make sense for us to do them, but we are in year 5 of the CPL's existence and I know before I could make a strong U-23/21 team with zero national team experience.
