I think that Rip covers both sides very well and it would, in my opinion, be unfortunate if we could only see one of those sides in the future. In fact I would argue that the information provided through his website/books/pod-casts/etc. distinguishes itself by a unique synthesis of real world experience / practical application AND analytics. You do not get this information anywhere else because most entities concerned with this topic are not nearly pedantic enough to provide analysis at the level of detail we are accustomed to here. Of those entities that may be motivated to provide such in-depth and high quality information about barbell training, its biomechanics and so on and so forth, hardly anybody has an equivalent amount of practical experience to put things into perspective.
Now, you have a point in that one may be able to win over a large percentage of people by just providing practical examples and observations. This is what most in this field are already doing and this may be the primary reason why that is the case. But for every example there are counter examples and the only way to make sense of all this is to look at what is actually going on. Without the analysis you can never make a compelling argument and move forward by continually refining both your application and your theory and letting both worlds inform each other.
