I think you're way overcomplicating it. Alex Morgan was far and away the best business decision. She's the most popular and recognizable female soccer player right now. She's young, relatable, and a role model for a lot of young girls, who are the target market for the addition of women's teams to the game. Solo has a lot of legal issues, Wambach is 35 and may not even play in the Olympics, Rapinoe is 30 and has never been the "face" of the team and isn't nearly as recognizable. Carli Lloyd was the best choice, but she doesn't have the recognition that Morgan does if you're looking beyond this one World Cup, and in reality, her one amazing game in the final.
Believe it or not, none of us are the target for this, and that's why so many of us have a hard time understanding it. EA wants to open themselves to a currently untapped market, and I think they're doing it brilliantly. Could they have added a more robust mode? Sure, but what 12 year old girl is going to think that? They're going to be thrilled that these teams were included in the first place.
