Agreed. He would really benefit from an editor. I think the usual recommendation for reading order is basically this: https://www.reddit.com/r/weightroom/comments/6g5m8o/book_rev...

For clearer writing and simpler programming, I would go for Tactical Barbell and Simple and Sinister over Wendler.

Doug Hepburn's programs (which can be found online with a minute of Googling) are also great for people looking at Wendler, but want something simple that can be run nearly indefinitely.
