Everything at Baseball America is behind a paywall and they seem to be the only site in the entire vast world of cyberspace to be looking at Cuban players who have recently defected or who may do so soon.
Cuban defectors who are close to the show, though, are generally the 25+ guys who sign as unrestricted free agents, not the ones signing as amateurs.
The current top-30 IFA as seen by MLB writers are, mostly, already signed, with the exception of Jelfry Marte (who just got cut because he wasn't healthy), and one other guy who is currently sixteen. Which is code for "useless and will almost certainly never play in the big leagues".
With Ohtani off the market and the top Braves cast-offs already signed or eligible to sign using next year's IFA budgets, 2017/2018 IFA dollars just went from priceless to completely and utterly worthless.
