Why can't anybody beat the maverick and the mavericks swept the heat and orlando god dang?

omg, the mavericks are in here. we are about to beat every team, i mean it's crazy because just by simply having dirk on the team their unstoppable, i mean this is their year to win this. They already beat the tops teams and whoever they didn't beat it's because dirk was hurt or something. so am I right, aren't they like the best team in the NBA?
