For Fournier if we extend him, it won't be to trade him I guess, so or it works and we keep him or it doesn't and it becomes a bad contract for years. And at 30 and 25M he won't be also a real trade asset anymore... TPE isn't a trade asset but we could take almost 30M of salary and give a bunch of picks and promising player if needed to get a better player at a more needed post (PF or C or a PG to replace Kemba). They were a lot of report that Hawks and Pelicans didn't want to pay Collinsor Ball...
For Smart I am not sure about what you say. I think he has a special story here. Couldn't he already have more in his last contract ? I don't remember. Whatever Hayward also had a special story here, but in the other way...
