I mean with salary cap maybe a few more guys will be willing to try NA path but the rule of thumb remains the same. If you believe you can make the NHL you earn more, if you won't you earn way less. That isn't going to change.
Altybarmakyan, for example, will be making less than he could in the K for sure. It's just that he played himself out of a big contract back home and the salary difference became marginal. Which, again, was always going to be the case. The only way that was going to change if the small KHL teams became richer and, hence, willing to pay more for KHL level talent.
