FTC has been around for five years up here in Auckland.
Overall mixed bag of coaching ability and from what I've seen - proof that having international coaching badges does not mean you have ability to relate to and effectively work with youth.
Plenty of talented players not in either Federation FTC programme up here in Auckland (AFF/NFF) because of doubts over quality of programme and cost. Player development and quality of coaches at some clubs significantly better than Federation level.
Because the NZF model is 'cost recovery' you end up with a large enough player pool in each FTC age-group to cover costs and this results in players who really have no place at the FTC (i.e. ones who lack basic ball skills) working with significantly more capable players. This is great for the weaker players who get the chance to work with quality players but both frustrating and counter-productive for those more able.
Couple all of this with Federation/NZF lack of interest in receiving or sourcing constructive feedback on the programme and you have a development programme that is great in theory, but no wonder plenty of senior coaches in football tell players not to waste their time in the FTC system and have the opinion that it 'breaks' players.
