In college basketball, roster turnover is virtually a given. I'm really not even talking about transfers, even though those have become a large part of the sport in recent years -- by Jeff Goodman's count, the number has gotten to over 700 players in the past couple of years, or roughly two players per Division 1 program.
With all those transfers come an opportunity. The old model of building a program with freshmen who stay around for four years, while not being archaic, is no longer the only option. Now, a coach with a scholarship available can bring in a transfer from another school who will come in with more experience even if he'll only be in the program for a couple of years.
