Problems with Grappling Books

There is nothinng inherently wrong with publishing a book on the subject of grappling, but when the quality of the book is decidedly low, then what purpose does the book serve?

The main problem I have noticed (and this is my own opinion based on what I look for) is that there is far too much emphasis on 'showing' a technique in a series of photographs accompanied by minimal text description.

What is someone going to learn from that?

Side control escapes

If there ever was one thing that was dramatically important for developing a strong game in the grappling/submission wrestling realm it would be the development of solid pin and side control escapes. Why?

If they can't pin you, how can they hurt you? Without pins, the only submissions that are a threat are the guillotine choke, toe hold and the bent armlock.

Think about that one
