Datsyuk was slated to make 5.5 million next year. I highly doubt he'll make more next year in the KHL
It's hard to find info about KHL contracts, but here's an article from 2013 that shows the highest salaries as:
Kovy: 10.3 mill US
Radulov: 7.5 mill
Zinovyev: 4.7 mill
As you can see, after the first 2 it drops off significantly.
And that's before the ruble collapse:
and the cuts to the KHL salary cap where the KHL president aims to limit salaries to 14.5 million per team. So Datsyuk's red wings salary would be more than a 3rd of a team's payroll:
apparently they're at 17 mill per team now and they'll cut the cap each year until 17-18.
If Kovalchuk is making $10,000,000 - Datsyuk will be making more than $5,000,000 - and this is why:
My very good friend played in the KHL for 2 years and was paid more than he would have made in the AHL/NHL on an entry level contract)... His bonuses were structured to pay him per goal, per assist, per regular season win, and per playoff win - and when all was said and done he actually tripled his base salary at the end of post-season...Apparently every player has an incentive plan that doesn't get compared in the dressing room, meaning it also isn't compared in the newspaper... Unfortunately, this league has also been prone to paying North Americans less than what they were promised - and good luck fighting the mob in a foreign country. Point Being: Don't trust any financial data the KHL put's into the press.
So yes, Datsyuk's salary might be close to what his NHL salary would have been next season ($5,000,000) - but he is also the KHL's highest profile player now (captain of the world championship/Olympic team) and will incur bonuses that far and away exceed this figure. I'm sure he will also do better with endorsements as well. Last year, he made $7,000,000 and maybe the $2,000,000 decrease was close enough to KHL money to say forget it... Which makes me question his character.
