You know, there's a way he could try to support his "logic." He could do a comparison of match-ups with comparable team rankings between neutral site and home/away games, and describe the statistical edge - if any exists - to home teams. He could compare the size of the effect to the edge implied by ranking differences, and the availability of relatively stronger opponents for neutral site versus home/away match-ups.
Funny that there wasn't such an analysis in that article.
