It does seem crazy that our sense of wellbeing in life is in part dependant on something we have absolutely no control over. If some football players in green do their jobs well we're over the moon, if they have a bad day and lose we feel miserable.
The NFL is particularly hard because of the win or bust mentality. There is only one trophy and fans of 31 teams end up failing to win it every year. The odds of seeing just one superbowl win are remote and the odds of finishing in defeat extremely high. Every year.
And the worst thing about it is the closer you get to the championship the worse the fall when you lose. If you thought the Giants loss hurt just imagine what it will feel like if we get beat by the Bears on Sunday. With a Packer team talented enough to win the superbowl. You will be in agony.
That is why there is some comfort in supporting a crappy team. Fans of crap teams never have to deal with the crushing playoff losses, the moments when they are fingertips away from the superbowl. And they have the long offseason to look forward to high draft picks and low expectations.
For the players and coaches this week, they can affect the outcome, they can train and plan. And if they lose they get paid millions of dollars and are off work for months. Fans have no control and when their dreams are shattered have to get up and go to work the next day.
