Overall recruiting rankings are not as important as getting right pieces. That includes the superduperstars, as well as the right complementary players. Uconn has consistently gotten #1 overall players and has had at least one #1 high school recruit on the team since 1994 (Nykesha, Shea, Tamika, D, Annie, Tina, Maya, KML, Stewie). And that doesn't include someone like Svet who wasn't ranked or Sue, who was criminally underranked or Stef, who's going on the Wall and will most likely be the best center in the country next year. UConn tends not to have top ranked recruiting classes because Geno doesn't like having a roster of 15 and is looking for very specific qualities (that he's usually right on in identifying, albeit not 100% by any means).
What Uconn doesn't have right now is the next game changing recruit. Stewie was heralded as the next great one, and she certainly has the potential to be. The question is: who's the next one, and can Uconn get her? I think Geno signing a contract extension helps more than another NC. A lot of kids come to Uconn because it's the place where you're most likely to be in the NC hunt. As long as Geno's in Storrs, that will continue to be the case.
