Yes, that's Miami missing seven shots on one possession... and that's Dallas allowing Miami to take eight shots on the possession... which spanned :54 seconds. Miami just kept chucking up threes (only two of the misses were from inside the arc) and Dallas got burned by a bunch of long rebounds because of it.
I can only imagine fans on both sides about :40 into this going "oh JESUS CHRIST... SOMEBODY DO SOMETHING!!"
Oh... Miami lost, by the way.
