[a073d2eb5cb24342493794d700e3dfc3]

In the new "Dream showdown campaign" you have to at least put down 2 dunks why is it I can put them down so easy everywhere else but I can't in these live events to move forward!? What is the deal? Anyone got any pointers to help me out on how to beat the system? Please
