Actually, let me start by saying that I have nothing against the refs, and I applaud them for the great effort and the countless good, close calls they've been able to make. But regardless of how many good calls are made, hell freezes over when a bad one is made, and after the Montreal/Winnipeg game, it's understandable why!
The refs on the field are part of the game, just as much as any of the players are. We here it over and over from Tom Higgins that they're competing, too, amongst each other for the top spot. I'm fairly sure we all saw the PI call at the end of the Montreal/Winnipeg game, and how it was complete bogus, and gave Winnipeg one last chance at winning the game. Why can't Command Centre not review this sort of thing? Penalties can have monumental effects on a game. Whether they decide a game or not, I'll leave at your own discretion.
I think allowing the Command Centre to hand over possession to a team off a challenge was a great step forward in the use of the Command Centre by the league. I think the next step forward should be deciding whether penalties were good or not. Not every single penalty on every single play, or anything like that, but at least upon the request of a challenge or in the final 3 minutes. I can only see good things coming out it.
