I actually did provide the Cup winners stat. But we can go a step further, in the last 10 years, of the 20 teams that made it to the SCF finals HALF were No Tax Teams.
Only 19% of the teams in this League have a no tax advantage. And yet no tax advantage teams are reaching the pinnacle of hockey success 50% of the time in recent history.
I’ve already suggested how you could increase this sample significantly further if you want to disprove the stats I’ve already posted. Go ahead if you want to disprove it and maybe you can teach me a thing.
Just because you're being intentionally annoying & obtuse about this, I did the work for you.
Here is regular season P% during the cap era vs the effective income tax rate in a given city/state/province at a $4M salary assuming no deductions (
US rate calculator,
Canadian rate calculator):
In case you didn't know, an R^2 of 0.019 is incredibly low, meaning there is
no relationship between regular season success and effective income tax
I did the same thing for playoff success in the cap era:
R^2 of 0.003 (wins) and 0.045 (win %) means there is also
no relationship between playoff success and effective income tax.
The 7 Canadian teams have averaged only 38.9 playoff wins per team in the last 20 years, while American teams have averaged 57.0. But what really kills your hypothesis is that the top 7 highest taxed teams in the US have averaged 62.0 playoff wins per team in that span, which is a fair amount higher than the rest of the US teams (57.8 excluding Seattle).
So it's not the tax system keeping Canadian teams down (and it's certainly not the entry drafts, Canadian teams have picked 1st overall in 30% of the drafts in the cap era despite accounting for only 20-22% of the league). I would hypothesize that the culprit is poor/desperate management, driven by pressure from owners & media. I think there are also a fair amount of American players who no longer want to risk playing in Canada after what happened with COVID, which has hurt Canadian franchises more recently.
Regardless, I hope you can accept that the data in no way supports your claim that the tax advantage is driving results in this league.
