Ignoring the basics is a common issue among strength coaches and trainers. As a strength coach, I often catch myself falling prey to this, by assuming that most athletes have the coordination and foundation of basic skills, although often these areas are greatly lacking. For example, it's easy to assume that athletes know how to jump. It's something they do almost daily. But based on my own experience, few athletes truly understand what proper jumping mechanics entail, and teaching them the basics such as arm drive and hip hinge mechanics can go a long way in terms of improving their performance attributes.
