I remember the "No goal" game in Buffalo when Brett Hull's skate was clearly in the Blue paint. Poor Dom, poor Buffalo.
Fast forward to game 7 in St. Louis, Patrick Maroon in o.t.. Blues advance to the Western Conference Finals. Rewind! just before Patrick Maroon's goal Dallas went down the ice, around the net for the wrap around waved off by the ref and confirmed by the overhead cam.
On the left side ice level replay it looked like the puck was up on edges ACROSS the goal line!
