He is really dumb for this reason...no matter how "good" negotiations go, it sets up "bad blood" between the player and franchise because the player says "I think I am worth this" and then has to hear all the reasons(some of which may be true that he doesn't want to hear) about why the team thinks he isn't and is only worth this amount. Those are things he may "hear second hand" from his agent but he wouldn't be present for the conversations and the depths and details that would be presented so he would mostly stay immune to that. There is a high probability this deal isn't getting done for this reason mainly.
