NOT get called all the time.
Watch what happens in front of the net on every play, someone is getting cross checked.
Pavelski had an awkward fall and got hurt, unfortunate.
But let me ask you this, do you think the refs would have given a 5 minute major if that was overtime? if it was a 1 goal game?
I think the call was made the way it was because of the 3-0 score, late in the 3rd period and they never thought SJ would score 4 goals.
At worst it should have been a 2 minute minor penalty.
