Query: publish or perish

This book bears the telltale signs of a work written under the academic duress known as "publish or perish". The author is a professor of medieval history and the book suffers all the rambling, roaming, and lack of focus of a dull history lecture. The author goes off on speculative and unscholarly tangents on the level of Von Daniken's "Chariots of the Gods". This type of activity is protected by tenure, but a dutiful editor should protect the public from this type of writing. The last chapter is the most irritating. Like a professor who has only 5 minutes left in which to finish his lecture, the author throws his unfinished thoughts into a final, short chapter. He had met his quota of pages and simply stopped writing. I wonder what kind of a mark the good professor would give this work if submitted by one of his students?
