You make it sound like "Today's NHL" = "O6 NHL" + 72% more of garbage players. IMO it's a ridiculous approach.
Thanks. I was actually responding to a poster who stated simply the (rather tired point) that "today's NHL is bigger and has more nationalities than in the early-60s so everything is better than a six-team all-Canadian League". Thus, I was attempting to point out, in response to said poster, that if, say, Alex Ovechkin (or any player of today) were to play in a six-team, all-Canadian League in 2020, the median level of talent on every team would, in fact, be higher than the median level of talent on each of the 31 teams today. And thus, the competition would not necessarily be easier, but might actually be harder.
In other words, I was attempting to draw a hypothetical parallel in 2020 to the NHL that Bobby Hull played in in the early/mid-1960s by demonstrating that in such a League today, in 2020, many of today's NHL players would be minor-leaguers.
It was then pointed out by some that the Canadian population of 2020 is three times what it was when Bobby Hull was born (it's actually about 2.5 if you look at when today's NHL players were born, c. early-1990s) -- the suggestion being that, in a six-team League today, the talent pool would actually be a lot bigger than when Hull played, and thus (I presume they were arguing that) for an all-Canadian League to resemble Hull's era in 2020, it would have be around 15 teams of all Canadians, not six (i.e., 2.5 times the six teams of Hull's era).
I then conceded that my own approach was imperfect, but also pointed out that it's not as simple as "more Canadians today, so more teams needed to equate with 1965", because it's not like organized hockey participation today is 2.5 times higher than in 1952 (when Hull was a kid). Others chimed in to point out that the bulk of the increase in the Canadian population since the early 1960s -- Asian / East-Asian skilled immigrants and their first- and even second-generation descendants -- contribute a tiny portion of hockey participation in Canada (at the higher-competitive and certainly pro-levels). In addition, it was further pointed out by other posters that the bulk of the pre-1970s superstar hockey players emerged from the rural and working-classes, a demographic that, in today's Canada, struggles greatly to afford the prohibitive cost of competitive minor hockey for their children. (Indeed, there is today in the NHL of 2020 a former 1st-overall Canadian player whose parents pulled him out of competitive hockey when he was a young teen because they couldn't afford it. Remarkably, he still ended drafted 1st-overall despite missing an entire year.)
So, while my original idea of a six-team all-Canadian League today was perhaps too simplistically thought-out (I concede I was wrong), the implied suggestion of a 15-team League is certainly too large to equate with Hull's conditions being moved to today's (for reasons summarized in the preceding paragraph).
Perhaps the truth lies somewhere in the middle: If today's NHL were about 11 or 12 teams of all-Canadians, then maybe
that would be the 2020 equivalent of the NHL that Bobby Hull competed in in the early/mid-1960s. Thus, the median talent level would probably be slightly higher or about the same as it is today, with 31-32 teams of international players.
To conclude: Hull's level of competition in the NHL (up to 1967 anyway) was about the same, or maybe slightly harder, than Ovechkin's today. Certainly Hull had no competitive advantage.
(NOTE: None of this results from my arguing for Hull over Ovechkin. I have no strong opinion about it one way or the other... my guess if that if I thought about it, I'd probably rate Ovechkin a bit higher than Hull by now. But honestly, the ranking of players is not that important to me. I find it all rather trivial.)
