I'm not sure drafted freshmen are really the metric. I'd say UConn had success with Sanogo, Clingan, Castle, Karaban, Hawkins, Solo and other recruited players. Many teams did. I'm not sure you can win with just transfers. But I don't think "break the bank" freshman are a good value, those are likely to get the most $ from desperate teams, like K-State.
It will be critical to recruit kids who are willing to play for modest pay and who will stay 2-3-4 years. I think a player like Furphy can pay huge dividends two years from now. Knowledge in the system, experience, really valuable. It seems like the challenge is that a whole lot of $50-100k guys think they can get $1M.
