The other big part of the 'Spanish System' is that pretty much all coaches are trained by the RPT, so there is a really tight, unified approach to teaching, especially around technique. If players are consistently given the same information, even from a variety of sources it only helps reinforce the important factors.
Most coaches here have no concept of a unified approach and will teach the same shot totally different to the next coach. Doesn't help the players, especially if they have one individual coach and a different squad coach for example.
