2015 Duke is the only team I'd truly classify as having been carried to a title by one and done players. 2012 Kentucky returned three of their best five players from a team that had gone to the final four the year before. Darius Miller and Doron Lamb were studs in college and Terrence Jones was (I think) a first round pick who returned to school because of the lockout. The only other team they've had like that has been 2015, which was obviously a juggernaut as well.
Even with Davis and Kidd-Gilchrist, that's like a four seed without the three guys I just mentioned. They essentially played six guys all year, and none of their freshman were especially gifted as scorers.
People also tend to forget that 2011 UConn is one of the youngest teams - if not the youngest - to ever win a title. Obviously nobody considers them to be from that cloth because of Kemba, but that's the argument I always used to make when people said you couldn't win a title with them - if Bazz, Roscoe, and Lamb had declared following the season, 60% of our crunch-time lineup would have been one and done (and I know that's not what people mean when they talk about one and dones, but if you follow the logic you can see the hole n the argument).
