That's another sports debate. Does the sample size of a regular season mean anything? No, not in relation to actually winning when it really matters. However, if we're going to use those accumulated fancy stats for short bursts like the Kings had, to show how much better they were likely to be than their competition, then the actual on ice results from 1,230 games also can't mean nothing.
A lot. We've also been scared of them actually winning in 2 of the last 4 years. Did people ask how easy of a road they had after lucking out against Vegas? Colorado, and then a bunch of other teams that can't win from the ever dangerous but overhyped "Thunderdome"? That's it? That's all that stands in the way of complete depression?
If the Sharks can't win, then it didn't matter if people didn't want Vegas to win more playoff games. Vegas is actually a threat, that will only get better because they paid a bunch of guys before winning. We should never worry about the Sharks winning again(their new contracts will take care of that), even if they're in Game 7 OT of the Final.
