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.
Playing time means stats means more money. That's where the agent is coming from. He's worried about the financial aspects of his client's second contract.
That "logic" eludes me. (not yours, the agents').
I'm not great on the CBA and the rookie scale, but first rounders are guaranteed money for 3 years. At the beginning of the third year, I think (like Young this year) the team can either exercise their 4th year option on the player (again a contractually prescribed amount) or allow the player to enter FA (I think, unrestricted) with no rights to him.
By the time any player plays his 3rd or 4th year, he should've had plenty of time to showcase what he can do, especially if he can contribute to a competitive team, unlike ROY MCW, who had great stats on a crappy team. What's his value now? This kind of goes against what these agents (LaVar Ball?

) are proffering about the Cs.
I guess that my point is that the NBA has watched players for years and many FOs know players' value by their measurable and the skills that they bring and their projected room for growth.
If a team has kept a player for 4 years (especially a team with the coaching staff and FO like Boston), it would behoove them to develop the player both as a trade asset and a contributor to a competitive team.
Now if someone wants to argue that CBS' system stunts development/future financial potential, then I guess that could be argued, but I don't agree with it.
