As said in several ways above, it's not the number of 5-stars you have, it's whether you can get them to mesh together into a great team.
Example that I've seen a lot: St. Mary's of California, who has gifted Aidan Mahaney to Storrs. Aidan was the Gaels' first-ever 4-star guy, yet SMC had won LOTS of games under Randy Bennett, even a few tourney games; often beating teams with 4-stars and 5-stars galore.
This sorta brings up another thing I've always thought about coaches. Some are better at "coaching up" so-so talent, but have trouble getting loaded rosters to jell. Some are better at making terrific teams out of highly gifted guys, but can't win at all with so-so talent.
This theory holds true for me in high schools, too.
It seems to me, in my as-yet limited experience with UConn, Hurley (and Auriemma) can be highly successful in both cases.
