Planning a program? How?

With the transfer situation like it is today, with players coming and going so fast that you have to have a program to keep up with the roster, how can coaches actually plan the future of the team with any success at all? Even at a high level, what with one and done. It has become somewhat like rolling the dice. Of course, when circumstances prevent coaches from following the course they ought to be following, they turn to other methods, and those will never be as successful, even though someone is going to win every year. Greed and a lack of patience have turned the sport into a dizzy carousel.
