1. Trade value is still increasing
This reason sounds a bit strange after praising Hardy in the previous slides, so hear me out.
Hardy hasn't really gotten to show his true potential at the NBA level just yet. He's only played one season with the Mavericks and some teams don't know what he's truly capable of yet. That's why I think Nico Harrison made it clear that they aren't trading Hardy or Josh Green - he knows that they can get so much more if they inflate their value over the course of this upcoming season.
Realistically, I think Hardy could become an extremely valuable asset for the Mavericks. He could even help Dallas net an All-Star-caliber player or first-round picks.
Right now, however, Hardy would probably only net the Mavericks second-rounders and/or bench pieces. I think once Hardy shows that he's capable of running an offense and starts in some games this year, his value could increase.
I could be wrong on this reason altogether, though, as it's possible the Mavericks end up keeping Hardy for the remainder of his NBA career. He's got such a bright future in the NBA.
I could see him ending up as a Hall-of-Famer. He's got all the abilities and skills in order to do so. Hopefully, Harrison and Cuban decide that he's the next starting point guard after Irving leaves and keep him here for a long time.
