Hidde van der Ploeg
In 1969 he was asked by the Nederlandse Volleyball Bond (NeVoBo) to become the head coach of the Netherlands men's national volleyball team where he applied his vision and training regime. The successes were mixed, but according to Van der Ploeg disappointing. After the 1970 FIVB Volleyball Men's World Championship he wrote an article for De Tijd about the Championships. In this article he criticized the team. This was not accepted by the volleyball association and Van der Ploeg was fired in November 1970. After a long search, the Polish Ben Krysik became his successor. He was offered a contract as coach at HVS in Haarlem that he accepted and later Van der Ploeg returned as coach for AMVJ.
