Once a player gets offered $80 plus million, he seriously needs to decide if the extra money from a so-called better offer is worth it. How much of the extra millions is he going to see, after taxes, anyway? So I can see if the player might decide on the best circumstances for HIM, instead of the best money offer. The 'smart' NBA players would consider that.
Recently, the Oakland Athletes signed 16 year old Dominican phenom, Michael Inoa to a large signing bonus to pitch for them. Though a small market, and teams such as the Yankees, Cleveland, Chicago, and others were willing to pay him even more, (the bonus money set a record anyway) the kid opted for the Athletics. Why? Because the Athletics have a history of nurturing young pitching, unlike, say, the Cubs, who have a history of destroying young pitchers' careers.
Some players just 'get' that it is a marathon, not a sprint.
