My response to talking about things in a vacuum would be: "who cares?"
Ok, but do you have proof that teams that win 3 in a row lose the 4th game more than 50% of the time? Or are you looking at a 4 game winning streak in totality? Because if you are, we're 3/4 of the way there and it doesn't matter that most teams don't win 4 in a row, because you have to win 3 in a row to begin with and the Rangers already did that.
