Buy This Or You're Dumb
It's really about that simple folks. I don't care what your defensive system is, 3-3, 3-4, 4-3, 4-4, Bear, Variable UFO Defense of Doomination, this book has something in it that you'll read, re-read, and realize that it's not only good, but it can help you. I read it in about 2 days, which is saying something because it's not a light book at 248 pages which are largely dense, technical football writing. It's not a book of diagrams and whatnot, it's friggin' WRITING. It's cheap, it's thorough, it's one of the best football books written in a long time.
So, What's It About?
Imagine if you could buy the basic, nuts and bolts knowledge needed to install and coordinate a defense that's flexible, multiple, and fairly simple. This is your chance to do that. It's no Tony Franklin System for defense, but it IS quite excellent for gaining a very functional understanding of exactly how Vanderlinden's scheme works. He gives you a thorough explanation of how they set and dictate the fronts, how that overlaps with the coverages, and how people's run responsibilities play out. Not only that, he gives you very easy to understand directions regarding how his defense would defend common run plays versus the different fronts that he runs.
That alone would be good stuff, very valuable for everyone's growth as a coach, regardless of scheme. But what I really, really like is he gives a pretty sweet explanation of coverages, techniques, and defensing some common routes that might be an issue. I'm the first to admit that my knowledge of DB play is quite limited. This gave me some really great insight into HOW some coverage components work, from a schematic and a technical perspective. I'm no DB guru now, but reading that was quite helpful for me personally.
Lastly, Vanderlinden explains a few of his favorite blitzes. I love blitzes, I love blitzing. One of the things I grew to love about running a 3-4 defense was how damn flexible it was for blitzing and blitzing creatively. Being a football coach, I love to steal, and Vanderlinden's got some good stuff. He explains them pretty thoroughly, which is cool, but he also explains a lot of his thought process behind them and when/why he uses them. Getting insight into the mind and motivations of one of the best coordinators around is precious information and he offers it readily.
Oh, there's also a fairly extensive section on technique for positions.
So, What You're Trying To Say Is...
First, buy this book. Second, read this book. Third, ???. Four, Profit!
