This year I think three super teams will dominate the discussion for most of the season. Last year the gap between whoever you considered #1, and #8 or #9 was not that big, say Arizona vs. Uconn or Stanford for example. This year 3 of the Final Four participants look to be not just a little better but greatly improved.
Obviously we are very excited with freshmen becoming sophomores, a great recruiting class coming in, only one significant loss (Anna) and if anything a much better transfer coming in (Dorka). We should be substantially better, but that is true of SC and Stanford as well.
Stanford is defending champion, and lost only one rotation player. Their two big time stars (Jones and Brink) return, they added a couple of good recruits. They should be better than the championship team. South Carolina may not have been quite that good last year, but could improve more than any of the top contenders. Everyone back, the #1 recruiting class at least according to ESPN, and the #1 transfer in Cardosa.
What is different for those three teams is I think they have separated themselves from the rest of the field, and I would be very surprised if the national champion came from anyone else, whereas last year it would not have been surprising at all and came close to happening with Arizona.
