Hidde van der Ploeg
Van der Ploeg became coach of AMVJ in 1968, and the team became in April 1969 for the fifth time national champion. Van der Ploeg saw international ambitions with the club. He wanted to increase among others the numbers of training sessions as some players only trained twice per week. After he came in a conflict with players his contract was not renewed in 1969. He improved his training methods while also working as a sports teacher at the university and as a volleyball trainer at the CIOS in Overveen. He became convinced that the Netherlands could become internationally successful with a stricter training regime and a different attitude.
