I'm not really anti NFL, I just don't want it in Canada. I have a hard time thinking of positives that an NFL team would bring to Canada other than making a very few wealthy "canadians" even wealthier. I don't think the NFL games are better. I believe the advantage that the NFL enjoys in talent, is trumped by the Canadian rules, making the Canadian game much more entertaining.
Maybe I'm a pessimist, but I believe that the CFL would not survive an NFL team in Canada, largely due to the massive media preference it would get. I also wonder about the psychological affects of having a long held canadian tradition wiped out by an american 'invader' on the national psyche. My guess is that the well known canadian inferiority complex would deepen considerably.
We would have to live with the fact that we allowed a cherished canadian traditon to be destroyed by our dominating neighbours from the south and profiteers from the north. It isn't just a football team that we would be importing here. It is an american cultural juggernaut, the most red, white and blue icon that the U.S. has, from the cheerleaders to the broadcast booth.
When the Dallas Cowboys (America's team) comes into Canada to play Toronto's NFL team in a Canada that no longer has it's own professional football league,(think of the symbolism) america's victory over a compliant canada would be complete.
A few wealthy "canadians" will be richer and canadian independence and cultural life will be much, much poorer.
