You don't want to reduce the size too much in one go or else the goalies are all going to blow for the first half of the season or maybe even more
This is adequate
It's too bad that this should lead to more five hole goals, those are rather unspectacular most of the time (yeah, yeah Golden goal, 2010, w00t w00t)
Toews will be digging it.
But seriously, I think it might give the opposite effect. Goalies know that their five hole will be a little more exposed so maybe they go down early a bit more often? Could leave more room for some top corner snipes.
