Disagree. I think that they'd probably lose, but they'd definitely have a greater-than-zero chance of winning.
The context of the question was that the Kings have had a full training camp, and half a season of playing together. And the caveat was that the ECAS don't get any time playing together: no tune-up games, no practice time, no nothing. Basically, it's a neutral court situation, and the ECAS all show up, like, an hour before the game. Best of One.
I still think that the ECAS would win, but it's not a "no chance" situation. I'd probably take the ECAS, -4.5.
