Our coach Max Caldas: "We want to give our players enough rest. After the national competition and play-offs and the Euro Hockey League, there is way too little time until the Champions Trophy, so we'll skip this year."
Furthermore, they got the invitation during the Hockey World League last year, but the technical director of the Dutch federation already immediatly said they wouldn't accept it. Mostly because the tournament would be exactly within the short time off/vacation for the Dutch team. Caldas then said they should go, but with a selection of players who would likely not make the Olympic team, so the rest issue wouldn't be a problem. However, apparently travelling to Argentina would have been too expensive, so they decided not to send any team. (and then it got changed to England, but the decision either didn't change or it was too late already)
