I tend to think that the player has the power over the agent, but the player can contribute to a complicated contract negotiation by being stubborn, indiferent or uneducated with the whole process. 
  
Stubborn like Crabtree that wanted more money that he deserved, the agent did what his client wanted.  
I also think that some players would tell the agent, "you're the expert, treat me right and give me what I deserve" and the agents tries to push for a little more hoping for more money his way.  
  
If this ends up this next week, we will never know, if it becomes a Crabtree situation we will know what really happens.  
  
I really believed this kid wouldn't miss a day of camp, guess I was wrong.
