No they wouldnt lmfao.
Harris is still a very good player. Yes, no ****, he is overpaid. Just because someone is overpaid doesnt mean they are a negative asset.
There are still plenty of teams who would take Harris if all they have to give up is matching salary and a late first. The Mavericks, for instance, have no feasible way to add talent to their roster. They won't have cap-space for years. They don't have good draft assets. They don't have good young players.
Are they a good trade partner? I have no idea. Im not going to run through every team's future cap scenarios/draft picks/etc to make dumb *** trades up. The point is that it's possible and could be something the Jazz, or another team, could look into.
