Agreed, but as we focus on future NT players, most of the time the first season 1v1 SF/PF is best. It creates quickly a strong level in skills that aspire most other skills, thus for a long-term training plan it is most of the time the best choice.
Once again, seeking advice is best, but most of the time when I am given a young player with high potential I strongly recommend going with 1v1 SF/PF at first. Sometimes more than an entire season !
