I dont think they would do it for MIA or Dallas.
Because those games could be sellouts and they could make a little money for once.I was at the dallas game,and it was close to a sellout.
I tried to go to a game vs Mia on the last home game of the season,but it was sold out.If they are gonna give discounts or free tickets ,it will most likely
be against some team where they will want to try to fill seats in the half empty arena.(Raptors,jazz, bobcats, blazers ect)
