How stupid were Heat fans to thinking?

That they actually had a chance to come back from 3-2 to the Dallas Mavericks? The Heat fans/bandwagoners were saying that the Lakers did it last year to Boston and that they can do it too. They forget that LA and Miami faced 2 different teams. LA faced a good Boston team, but they were tired. Miami faced Dallas, who is a deep team and Dirk was on fire and beasting on the Mavs as well. Heat fans fail to recognize and see that, but most of them are dumb anyways. How dumb were these Heat fans into thinking they would come back? Dallas had all the momentum too
