You must be joking, WestCoastEasy. Listening to stumps fans whine and moan about the natural grass field in Edmonton after they get their butts handed to them is one of the most satisfying things about an Eskimo victory over crygary!!!
It's even more amusing to listen to their excuses when they lose a Labour Day game or playoff game in crygary. No grass to blame it on. It is invariably the refs, or injuries. Has anyone ever noticed how winners and champions don't need excuses?
Anyways, the natural grass at Commonwealth is world class, and good for many sports other than football, including soccer and track and field. Edmonton hosted the World Track and Field Championships in 2001, I believe. It is the third largest sporting event on Earth, behind only the Summer Olympics and the World Cup of Soccer. Much larger than the Winter Olympics, as measured by TV audience, number of athletes and number of participating countries. I do not believe that such an event could be held on any artificial surface, when you take into account javelin and such. Keep the grass in place, and let the visitors whine all they want. If it provides a psychological advantage to The Mighty Edmonton Eskimos, so be it!!!
