There's no need to be defensive or feel insecure on either side of the argument. It seems like some of you sound threatened by the other. CFL fans have no need to fear the growth of soccer and the MLS in Canada. On the other hand, MLS is growing by leaps and bounds, will be a huge success, and will also become a big part of the sporting landscape and culture.
The fact is both Lions and Whitecaps are here to stay. To say that the Whitecaps will take over the Lions place as #2 in town would be premature as the Lions and the CFL are firmly established entities in the Canadian and Vancouver sporting landscape. The Lions are the oldest pro sports team in town and the CFL, in its current form, has been around since the 1950's. This gives Canadian football a type of continuity and presence that Canadian soccer has lacked for decades. Give MLS and the Whitecaps a decade or two and you will see the same type of TV numbers (for all-Canadian games) and support that CFL and Lions command right now if not sooner.
Though the Whitecaps have been around in one form or another since 1974, they have just returned to the top of the competitive ladder in N. America this year. Add to that the fact that MLS as a league has only been around since 1996. That said, there's every indication that the Whitecaps are going to be a success both on and off the field. With the changing Canadian demographics and the global appeal of soccer fueling interest in the game, the Whitecaps definitely have immense potential and a storied past to build upon.
The TSN TV ratings from last Saturday are misleading, this was the FIRST all-Canadian broadcast for a new team in a relatively new league. Also, one must consider that MLS only has 2 Canadian teams and will likely max out at 3 teams after Montreal joins next year. MLS is still a regional/urban league with a following centered in those 3 cities. It is reasonable to assume that the majority of viewers of the game were from Vancouver or Toronto. I don't think too many people were watching in Riderville Regina. 300,000 is a great audience, all things being considered and bodes well for the future.
The CFL has enjoyed a much longer history in this country. You can't deny or forget that the game has 100 years of history with the Grey Cup. 100 years! The league has 8 teams spread across the country and enjoys a large rural following, particularly in the prairies. With that much history and national coverage and support, it's expected that the CFL has a larger following than MLS. One can assume that much of the viewership of CFL games comes from a national audience. It would also be very interesting to see a regional breakdown of TV audience numbers.
Will the CFL continue to enjoy its important position and stature in Canadian sports and more locally in the form of the BC Lions? Yes it will. Will soccer, MLS, and the Whitecaps continue to develop and firmly establish itself? Yes it will. Will both sports continue to thrive in Vancouver? Yes, there is enough fan interest and corporate dollars for both. Will the Lions drive the Whitecaps out of business or will the Whitecaps usurp the Lions #2 position? No. Having been born in the 80's I can't say for certain but from what I can tell both Whitecaps and Lions enjoyed a similar importance to Vancouverites in the late 1970's and early 1980's. Also, don't dismiss the fact that many MLS fans are also CFL fans and vice-versa (myself included). I tend not to think of the situation as being Canucks #1 and a battle for #2, but rather #2a and #2b with Whitecaps and Lions being both complementary and competitors sharing roughly equal importance and positions. Each with their distinct target demographic and fanbase but also both with overlapping support.
There's room for both the Lions and Whitecaps in Vancouver and both will continue to flourish and grow. In fact, a little competition is good as it will force both organizations to continually improve. The result will simply be a better product for everyone involved and WE as fans, whatever your flavour, will benefit. So let's all chill out, enjoy the show, and celebrate the championships that are to be won!
