When Memphis beat Houston with a buzzer beater, half the building did not think that the game was over. Houston already gave away an 18 point lead to Atlanta, and now they are losing to their main competition in the west to get a shot at Golden State. The issue is that the Rockets do not believe that they should be losing these games. They keep finding ways to lose these games, and they do not know what to do.
There is no way to know if the Rockets will grow up, but I think that it is not going to happen. They seem a little too immature.
