Big Hat Tip to Henry Abbott for this.
Read, the first article, and most of it is about Kevin Love actually. The interesting part is how it pertained to Donte Greene, and his uncle (who got a loan in part of the agency that tried to get Greene to sign with them).
This quote, though, by Henry Abbot may be the motherload:
The truth is that recruiting players -- the wooing of friends, family, AAU coaches and the like -- takes an agent's time and money. That's time and money they can't spend on existing clients.
Young players could fix all that, because they can choose any agent they want. They have the power. My recommendation would be to choose the agent who does the best job serving existing clients, without wasting time on those who are hell-bent on showing you a good time.
