Here is where the book’s greatest failing is. In trying to tell the story of Lionel Messi and why he is great, the authors hammer home using statistics and graphics data points about his career. None of that matters to kids; kids find their heroes through watching them and then comparing with their friends. As a child of the 1980s, my heroes came from other sports, like baseball. I didn’t admire Nolan Ryan because he ranked at number whatever on the all-time strikeouts list or led the league in some statistic. I liked him because he threw fast, struck out a lot of people, and was a winner.
