SDSU lost at Wyoming who is a better team than NW and its one of only 2 losses (Wisky has 5, three at home). WSU has no great wins, but they are undefeated and off a season where they went to the FF. They are better than Wisky and Iowa. Villanova beat Iowa (and Kansas in the Bahamas). I think Villanova is a questionable top 10 team (9th in one poll, 11th in another), but they only have 3 losses, some good wins and beat Iowa who I am supposed to be comparing them to. Cincy lost to a solid NM team (they would be in the tourney right now) and cross town rival Xavier. Their 3 losses are to top 50 RPI teams . FL had injury and suspension issues (Finney-Smith and Wilbekin dind't play and several others did play but were coming off injuries). Wisky wouldn't stay within 10 points of them on a neutral floor today.
There is always room to make an argument that teams ranked 11-20 may be as good or better as teams at the bottom of the top 10, and this year is no different. The top of UW's resume looks good until you consider the that the wins against FL and MSU were at home and with each opponent missing 2 starters. They look like a top 10 team when all 5 starters are making threes, but they don't really have anyone that can create their own shot and that shows in how low their scoring has been against better teams. Iowa is 2-6 against the top 25 (they lost to Villanova), so they don't have any bad losses, but the 2 wins were against teams they also lost to and top 10 teams should have a better record than .250 against the top 25.
Iowa and UW could make a run at the end of the year and show improvement in areas they have been weak. Right now, .I don't consider them top 10 teams, but there are teams in the top 10 that are vulnerable. There isn't a noticeable gap in the in the pack from the top 8-10 this year like there was last year.
