See? Perceptions on this board are just that : perceptions.
The numbers are not an exact science but give you an idea.
Number of shots is not important. Sens don't close the outside lanes so they receive many shots from bad angles. In 2012-13, they played a very tight system and were very efficient. They have shown a bit of that this season but offense is lacking and isn't building a lot of momentum so have to do some extra work in the zone.
Get used to it, the world is about to implode. Human race is helpless.
