This Cavs team has a lot different personnel than their teams from the prior two years. IMHO, the reason they're down 2-0 isn't because they have the same psychology as prior years' Cavs teams, but because they have not jelled, because of (1) the Varejao and Pavlovic hold-outs, (2) the big trade, and (3) injuries.
That having been said, its totally stupid to get LBJ riled up by chanting. It's like those two drunks who annoyed the Siberian Tiger in that Cali zoo a few months ago: the tiger jumped the moat and ate them. Stupid, stupid, stupid.
