As a general rule, a still photo doesn't tell you how the body is loading and unloading. There's no way of knowing how this pitcher got to this posture nor can it be determined what this pitcher is going do to finish to throw. This pitcher has potential to throw very hard, or, top out in the mid 80's...it's a coin toss.
Funny. I own the same book and thought the same thing. It is a very good book and the photo may have had nothing to do with the author at that point. An interesting choice none the less.
