Initially, I agree that it sounds odd, almost sacrilegious to feature tactics with strikers on a site called Strikerless and dedicated to playing without actual forwards. If you allow me time though, I hope to explain why this diamond formation is not really that different from the usual strikerless style of play.
The diamond formation provides a solid platform through the center of the field. The staggered diamond in the midfield allows the team to keep possession of the ball with intelligent player movement and good short passing. The whole formation thrives off of mobility, vertical movement and physical prowess. That really sounds like a lot of the concepts I mentioned in earlier articles.
