My thoughts after watching my DD's first 4 games in D1 is women's soccer is a lot like college football. There are only a handful of teams that have a legit shot at winning a national championship due to the collection of elite players on those rosters. The top teams may have 6-8 truly elite players surrounded by a roster of very good players. Other teams may have 1 or 2 elite players if they're lucky but most D1 rosters are comprised of 2-4 really good players surrounded by a roster of above average and average players. Watching my DD's and her former club teammates games, it's obvious how large of a gap there is between the top and the rest. My DD's team has several really good players but roster depth is the difference I have seen when it comes to competing against the top teams.
And MAP I'm still holding my opinion on the undefeated teams at Arizona, ASU, WSU, OSU, Colorado and Cal since they haven't been challenged yet. The opponents they have beat will not help their RPI's. The combined record of their opponents is 10-53-12. Unfortunately I only see a max of 6 teams getting in due to the middle of the pack teams not being helped by their out of conference opponents. I hope I'm wrong...
