The way iginla reacted was exactly as to be expected. The flames were getting dominated in every aspect of the game and regardless of his personal effort, the team just was not responding. He was frustrated, and was trying to take his frustrations out in an effort that would help motivate his team. Hopefully the team can respond to the emotion next game, if nothing else.
Although I would tend to agree, the history between the flames and mick mcgeough isn't the prettiest. He was probably the last ref that flames fans, and players, would have picked to call a game. I'm not saying that old mick has a vendetta against the flames, but sometimes the emotions get the best of you, especially at a time when the stakes are so high.
