It hasn't been happening for years. It is a new fad over the past 5 years. Hinrich was going to ISU until Floyd left and Collison was going to Iowa until he Mr. Davis was asked to leave. LaFrentz was the only big time recruit who left for a long time.
Now a days kids take the easy way out of going to Carolina or Duke because it is easier to win there, they don't want to rebuild something.
Please don't tell me that they can be part of something "special" at Duke, Carolina, Kansas, Kentucky etc..... It isn't special to win a title at those places they are suppose to. If you went to an Iowa, Minny, Illinois, ISU, etc.... and win there that would be something special. You would be remembered forever.
