Agent has a fiduciary responsibility to get his client the highest value. Obviously, client will be overjoyed to be drafted by a top organization like the Celtics and....oh lookee here, get paid millions and millions of dollars by a top organization.
So Mr. agent? You want your 19 year old client to start next year and get clocked night in and night out? Lose over and over again?
Avery Bradley fought his way onto the team. Learned to play the right way and is now one of the better two's in the league, not to mention probably, one player most coaches want on the court in a playoff game.
Why would an agent want that?
Brown has got a ways to go and he is working with the right people to get him there.
Your client might get traded? What!? Pretty much everybody gets traded.
"We don't want to get traded to the wrong team."
Take your 3% of the mountain of money your client makes and shut up.
