Some are acting like the series is over. Not yet, and that has little to do with past Caps history of losing 3-1 leads. The Caps have also come back from being down 3-1; and 2-0 in this very playoff season.
It has to do with simple probability. Say Vegas has a 45% chance to win any game. You can debate weather that's too low or high but that's a reasonable starting point. Then there chance to win 3 straight is 9.1%. If they get favorable reffing in games 5 & possible 7, that figure will be above 9.1%. Not exactly lightning striking. Of course winning game 5 will roughly double their chances to pull of the comeback.
Not being positive or negative, just
realistic. GO ALL CAPS !
