There are so many factors you are ignoring here...facey wroteCOLONIt's the same for everyone, I struggle to see how that's unfair.
Yes it is a smaller 'sample-size' of gp for comparing the statistics for two teams, but even a normal week is based on who gets hot, sometimes even for just 1 day... so no it's not ideal, but it's also not biased.
The hottest offensive player in the NHL ran cold this week, the two coldest players on my team woke up with goal(s)... it's random as always!!!
The GP differential is less meaningful over a 7 day stretch than it is over 3 days based simply on total games played, not to mention that players nursing injuries, and more specifically goaltenders are less likely to start during this stretch so as to gain a longer rest period (over ASB) than they otherwise would have, a prime example is Andrew Ladd this week, or the almost scenario with Raycroft and Vokoun. Not to mention that the best teams win FAR MORE OFTEN than not over 7 days, I'd wager my house the odds are far less in favor of the better team in 3 days.
Furthermore, when you have a team full of 20 players, hot and cold streaks tend to balance out over a week, over 3 days the HOT team will win far more often than not, if not every single time.
You continually bring up that it is the same for everyone but that is not necessarily the case...The difference in games played, injuries, and opponent during a shortened week demonstrate that, you can argue that it is the same for every week, but as I have pointed out above, those differences are heightened during a shortened week and can potentially ruin or unfairly alter tight races down the stretch.
Place yourself in the worst case scenario, would you be completely satisfied with the shortened week?
