I take offense of your Habs troll comment BTW. You should shift your focus.
Cool. I'm a Habs fan too. I think Habs fans should shift their focus to the team's horrid management instead of whining about taxes, especially considering the primary argument is always about UFAs and the Leafs just signed the best one in a decade with basically the same tax rates. The Rangers and Kings were perennial contenders with tax rates a percent or two lower, the Ducks are (were?) always good despite top 5 tax rates (and an internal cap!) and the Jets/Leafs are currently among the elite teams in the league despite taxes that are only a half percent lower than Montreal (and in the case of the Jets, a substantially less attractive city). My position isn't "tax rates don't matter", it's that I don't think they're a primary factor in the Habs lack of success or something significantly hampering the team and I think they're very far down the list of problems for the amount of discussion they get among Habs fans.
Even with the highest taxes in the league the Habs already have a massive financial advantage over other teams. They can't ensure as much post-tax payroll in a vacuum as Tampa Bay but the fact money is truly no object to the Canadiens (and Leafs and Rangers) is a huge advantage and they've used it a lot recently. A lot of teams couldn't afford to pay Therrien over 4M to stay home and then shell out 25M to sign Julien for 5 years. Lots of teams can't afford to sign a bunch of AHL ringers for 925k each (and pay them 300-400k in the minors) to bolster their AHL team. Lots of teams couldn't afford to give Tavares the exact contract structure he got, the Habs could have and absolutely would have if they had the chance. A lot of teams couldn't afford to trade for Weber a week before he was owed an 8M signing bonus, or offer Price 26M in signing bonuses in his first two years. A lot of teams couldn't afford to do the Mason+Armia trade, the Habs effectively paid 4.5M in buyouts and salary to buy a signed Armia, a 4th, and a 7th at the drop of a hat.
Price at $10.5M, Subban at $9M were deals that were more than most thought would be signed (including non Habs fans). Now look at Hedman, Stamkos, and Kucherov contracts. Of course the team you play with has a factor (Tavares in Toronto for example) but ignoring the difference is taxes is not something Habs fans created. It's been a topic of conversation for years now.
Taxes aren't the reason Subban and Price got the biggest AAV for their positions at the time they signed. It was because the 2012-13 lockout added contract limits so it was no longer possible to front-load deals, and Subban and Price just happened to be the first elite guys around their own age cohort to get close to UFA status. At the time Doughty and Karlsson were signed long-term on deals right after their ELCs so they were far from arbitration and UFA rights and didn't have the leverage to get 9M like Subban. Now that LA has to pay for Doughty's UFA years they're spending 11M for them, and Karlsson will get about the same.
That's basically what the past generation of elite defensemen got as well, but it was just masked by those front loaded cap circumvention deals. Over the first 8 years of Shea Weber's contract he got 92M (11.5 AAV), and for Suter it was 80M (10M AAV). Same for Price, Lundqvist's 8.5M is about the same as a percentage of the cap as Price's 10.5M. Price was just the first of his generation of elite goalies to sign a contract as a near-UFA and his peers (Holtby, Bobrovksy) just haven't got a chance to cash in yet. I expect Holtby and Bobrovsky will get similar money in the next couple years.
