Why are Miami Fans saying they will 7peat?

A few users, most notably D-Wade all day and A LBJ fan, has said that the Heat will 7peat. LMFAO! Good luck with the young teams emerging like Bulls, Thunder, Warriors even, Clippers, and Knicks. And the veteran teams like Boston, Dallas and the Lakers still here. Yeah it's pretty clear that a 7peat is almost near impossible. I don't get why Miami fans believe this. They must be stupid or delusional you guys agree?
