Well, I will certainly admit to some amount of ignorance on this tournament. As a non-sports fan, especially golf, I can honestly say I've never heard of this playoff and that's why I was surprised it was being held in Montreal in September, when the weather there can be quite changeable. It has nothing to do with being against Canada, a conclusion you always seem too fast to jump to.
I may not be a big fan of the output of Canadian TV, but I'm still very glad to live here and be a citizen, especially if you look at what's going on south of us. But I digress.
I will also agree with your contention that NBC would rather air this than any of its regular programming, because live sports always does well in the ratings and brings in more cash. Still, 11 hours of anything is excessive. It's just too long to take up valuable airtime with one thing.
But there's also something to be said for having local and network news avails instead of constantly interrupting these shows every weekend for some endless event that never, ever, ever ends on time. (Much like the NFL on Sundays, where CBS is forced to super a warning to viewers every few minutes that one of their upcoming shows will now start at 9:37 PM because of the endless delays. Too bad if you set your DVR and miss the ending!)
Local stations make revenue from their local news, which is expensive to produce. Constantly interrupting it means those spots never run and they lose money, while also not serving their community. At least make room for the 6 o'clock news.
There's no doubt I'm in the minority on this. That said, if it was just once in a while, I'd be OK with it. But it's now every bloody week and it's becoming really annoying for an otherwise regular viewer. There is simply no reason for every single U.S. network to air College Football on Saturdays. Five different networks (including the CW) essentially with the same choice (which is no choice.) Whatever happened to competing by offering something different? As my viewing habits prove, not everyone is a sports fan. You gotta serve those viewers, too.
