Well there's only 8 players in the league with more game winning goals than Crosby this year
We know how flawed this GWG stat is. Your team can score 5 and yours is the second one, and then they score one back, and you end up with GWG in the stat sheet.
Or you score a goal to make it 5:0, and then your D gets too relaxed and the other team gets 4 back, and again you end up a saviour, while in reality all you did is only scored an easy goal on an unglued opponent.
I prefer to use eye test. And it shows me, that in so many games recently vs good teams, playoff bound teams - when Pens needed a goal - Crosby was nowhere to be found.
