Query: Horribly organized and written

Highly disappointing. I'm an intelligent person who knows nothing about football but now wishes to learn, and this book was useless. Almost immediately, the author started using football jargon that was never defined, even in the appendix (and I was reading it on a kindle so was able to search). Poorly worded - I found myself reading a few paragraphs multiple times trying to deduce what the author was attempting to say. Very nearly unreadable to someone coming to football with a blank slate. I wish there were a way to indignantly demand my money back.
