If you look at this guy's stats, he's faced 346 shots in 16 games, with 331 saves. Besides this being a ridiculously short sample, in any case this guy faced less than 22 shots per game on average. Seems like he's got a good defense...
There's another goalie, Alexander Samonov, who also played 16 games, has a similar sv% (95.3%, vs Bilyalov @ 95.7%) but faced 516 shots or more than 32 a game on average. This looks more impressive to me.
There's yet another goalie, Vasily Koshechkin, who has played way more games (32 = double the games) than these two, still retains an impressive 94.2 sv%, while facing 29 shots per game on average.
Furthermore, it seems like goalies in the KHL seem to have an inflated save%: 2 are above 95%, 4 are above 94%, 10 are above 93%, 15 are above 92%.
There's 14 goalies in the KHL below 2.00 GA, in the NHL there's 2 (and the top one would be tied for 12th in the KHL).
I mean, this guy might be something special or might simply be the product of this league. I would put money on the latter, if I had to.
