Quite a few.
Calvin Verdonk to FC Twente - expected to move on to the MLS in January.
Dylon Vente to RKC - well if he scores 10 or more goals, he'll be taken seriously for next season.
Bart Nieuwkoop to Willem II - if he does well, then we might see him back for next season with Karsdorp just being on loan for the season.
Crysencio Summerville to ADO - at 17, maybe he's the guy with the biggest chance of all of making it. Early days though, but he has already made a subs appearance for ADO.
Ramon ten Hove to FC Dordt - they apparently already want a new goalie. That doesn't bode well
At Feyenoord, Elber Evora is probably higher then in the hierarchy.
Jordy Wehrmann to FC Dordt - there was talk that ADO would take him on loan but that didn't materialize. Maybe we'll see him hover around in the end at a club like PEC like Gustavo Hamer.
I'll update this thread if any of these guys do anything amazing or stupid.
