It's normal to have some inconsistencies in these rankings. If you add in blue star, rankings swing toward UConn:
BS HG PN
1 1 1 Megan Walker
8 13 31 Mikayla Coombs
10 16 32 Andra Espinoza-Hunter
21 29 22 Lexi Gordon
3 2 2 Evina Westbrook
9 7 6 Anastasia Hayes
26 12 9 Rennia Davis
22 57 11 Kasiyahna Kushkituah
Overall class ranking means very little in the grand scheme of things. Look at the last 5 years of top classes:
2016-Maryland, multiple transfers already including best player
2015- Duke, top player leaves after a year, Primm transfers too
2014-UCLA, stayed in tact, doesn't appear to be a Final Four type of team though
2013-North Carolina, all 4 players transferred
2012-Connecticut, Jefferson/Tuck/Stewart all stayed and won 4 titles
2011-I think Tennessee had the top class with Burdick, Massengale and Harrison...all stayed, Izzy was the best but they weren't able to reinvigorate the program
2010-I think it was Duke, the class all stuck together but had underwhelming results, largely due to injuries
2009-No idea
2008-Tennessee and Rutgers had the top classes. This went on to be Tennessee's first class to never make a Final Four, and this class also started Rutgers downhill decline
2007-I think again in was Tennessee with their class of Cain, Bjorklund and Baugh. Injuries derailed Cain and Baugh, even though they had some very good moments. Bjorklund was quite overrated in hindsight. They won 1 title on the coattails of Parker and company, but never were able to get Tennessee back to a Final Four.
Out of 40 teams who have made the Final Four the last 10 seasons, programs who had a #1 overall class ranking on their roster make up a grand total of 5 of those 40 teams. 4 of those 5 were Connecticut's 2012 class, and the other team made the Final Four on the coattails of their upperclassmen.
In summary, having the #1 overall class ranking doesn't mean squat.
