The NFL should merge with the CFL (Canadian Football League) if it is looking to expand

I'll be brief as it is late (at the time of the argument against) but it piqued my interest.Difference in codesGridiron football evolved from Rugby football, and like Rugby football Gridiron split into two variations: American and Canadian. Like wit the Rugby chasm that developed League and Union to the point they can no longer be, both Gridiron codes slowly developing independently to the point the likeability of a merger can be rendered moot.https://en.wikipedia.org...(I can source Wikipedia, right?)National identityWhile Canadians have not much to say about the US in either a positive or negative light the thought of the NFL consuming their own gridiron league and "Americanizing" it with oversaturation of pop-culture may be a turn-off for them. Canadians see their own version of football as some sort of independent sport, and the idea of mainstream American pop-culture and commercialism absorbing their league may be a turn-off for many.http://www.bbc.com...NFL should be exclusive to the USThe NFL- and the sport in general- has a history of completely failing to appeal other nations outside the continent with the American gridiron code of football. NFL Europa and the World Bowl are prime examples of how little the world outside the US cares about it, resulting in massive financial losses thrown in on renting Wembley Stadium. At most, the only success they have is in Germany but even then they only have at most 10 teams playing semi-professionally and the NFL aren't too keen on scouting them. Canadian football has always been seen as second-tier at best compared to the NFL and I doubt a merger would happen with the elitist mndset the NFL commitee have. That, and the popularity of other sports such as association football (soccer) and the aforementioned Rugby overshadow gridiron football in foreign lands, not to mention the over-commercialization that makes up for 50% of the games and the constant stop-start gameplay that extends a 60-minute game into a 3-hour broadcast (intermissions not included).http://www.forbes.com...http://business.time.com...Regarding your rule of "Con CANNOT argue that the NFL shouldn't be expanding in the first place." I'm not saying NFL shouldn't expand per se, but that they have a history of looking into implementing gridiron football teams and culture where no one cares about it and failed horribly at it. They should stay at home and be looking at football hotbeds like San Antonio or no-man's land like the states of Maine and Alaska (but not Hawa'ii, that's too far) to expand their league. No rules broken there.Seasons (temperature, not league)The biggest flaw you overlooked are seasons. Due to their close proximity with the Arctic Canada during the winter is extremely frigid and if a merger DOES happen it is likeable that the Canada-based teams have to play during the cold season exposed to the snow per NFL regulations, risking the players to develop hypothermia and other health-risking symptoms. This is one of the main reasons (if not the only reason) why the CFL plays from Spring-to-Fall to avoid the extreme temperatures while playing in the much warmer climates during the summer.Anyway, get ready! I'm passing the ball to you.
