So ignoring the fact that Marcus's agent should have any fiscal common sense, he'll firmly advise Smart not to do anything like this again. His little tantrum certainly cost him several million dollars. It also sets an undoubted precedent that Ainge is probably not going to go that much higher than the previous offered contract, that Smart rejected before.
So in all in... Very upset Smart did something clearly not as 'smart,' but... It is definitely gonna bring down his value, and some teams are going to see his firey temper as a net negative. (Considering he has done this before, and his Oklahoma days.)
