I mean, I can totally see him staying if he's getting paid more money there. But he's not a superstar level prospect. He's not a Kuznetsov or Kaprizov type who's getting locked down by CSKA and other top tier clubs and getting money thrown at him. He's playing for a relatively middle tier (financially) team who is veteran-heavy and he's never been touted highly enough to warrant a huge payday. If he comes to NA, chances are at some point next season, he's going to be an NHLer and he's going to make upwards of 800K+.
If someone's familiar with his proposed contract from Salavat, I'd love to know what the numbers are that are being thrown around (In USD).
