The fine for this penalty was following game 3, in which Ryan Suter had shoved Andrew Mangiapane in the Stars netting. Benn, the troll saw that Mangiapane was pressed into the net and poked him a few times with his stick.
George Parros and Toronto, certainly don't have the favor of fans and they seem to always be inconsistent with rulings and different players. This situation is something the league likely hasn't seen before, but is a dirty play the league would like to remove.
