Very true Ray ... oddly, the best rider in the world won't always make the best coach / instructor.
As I think someone said earlier. Getting the basics sorted is like building a house with good foundations, it enables you to progress. These basics are often the areas which make the biggest difference to peoples everyday riding, they're also the bits which are easily overlooked. Change a few little bits and the positive difference can be quite dramatic.
When you're riding nothing exists on its own, riding a drop without the ability to control the bike afterwards (perhaps braking, cornering, etc may be required) may still result in a crash. If someone asks for a days instruction in riding drops, we don't go marching up to the drops straight away. There's a build up of skills and techniques (mental and physical) to get them there ... if there wasn't then every instructor could just hand out the MTFU speach and leave you to it
