As far as opinions on talent goes, Canadian NFL fans are a pretty unknowledgble lot who know little more than the betting lines and general hype as far as pro ball goes in my experience. and any talent disparity is neglidgible based on their view.
American NFL fans and Canadian CFL fans know pro ball. Have never met an American who said anything negative about the CFL ...and their opinions range from curiousity , to weird to "we should adopt that rule"
Less than a thousand tix left for Grey Cup and Esks fans travel well as they throw the best party but luckily some dejected Bombers season tix holders are flooding kijiji with their tickets
A week from today the Ottawa Redblacks will be World Champions
That's a pretty heavy handed generalization to toss around.
I definitely know the type you're referring to you generally just know the betting lines and general hype but that's not a NFL fan thing, that's a sports fan thing. Of course the degenerate gambler type will flock to the NFL, it's the 'best' sport/league for that. Personally, I'm not into that nor are my close friends and family who I watch football with. I'm big into fantasy, but I spit in the general direction of the daily fantasy scam and convinced a lot of friends not to get involved.
So, my anecdote differs from yours. I actually don't know many knowledgeable 'Canadian Football' fans. Just my friend's dad who took us to games back in the Renegades days. I had to explain the concept of a safety and field position to a bunch of season ticket holders at the end of the half yesterday. I know that the people I've been exposed to don't really represent ALL CFL fans though. They're mostly probably in Western Canada and maybe Hamilton, where I don't visit often.
