Still with me? Let's go.
Taking these numbers, we can look at projected (this is very important to consider) point totals for Valentin Zykov, Andrei Svechnikov and Martin Necas.
Points in the American Hockey League translate at a 0.486 factor (and this number has been calculated using a great deal of data, considering the number of players who have progressed from the AHL to the NHL). In 2017-18, Zykov totaled 54 points in 63 games with Charlotte, a scoring clip of 0.857 points per game. Multiplying that by the translation factor, we get a scoring rate of 0.417 in the NHL. Over the course of an 82-game season, that would equate to 34 points.
Points in the Ontario Hockey League translate at a 0.323 factor. In 2017-18, Svechnikov recorded 72 points in 44 games with Barrie, a scoring rate of 1.636 points per game. Multiplying that by the translation factor, we get a scoring rate of 0.529 in the NHL. Over the course of an 82-game season, that would equate to 43 points.
Translation factors from the Czech Extraliga are tougher to assemble. Vollman does not provide an era-adjusted translation factor (as seen above for both the AHL and OHL), but based on an extremely small sample size, he calculated a 0.457 factor that we'll use for the purposes of answering this question. In 2017-18, Necas totaled 17 points in 24 games with HC Kometa Brno, a scoring clip of 0.708 points per game. Multiplying that by the rough translation factor, we get a scoring rate of 0.324 in the NHL. Over the course of an 82-game season, that would equate to nearly 27 points.
What to make of these projections? Well, for starters, they're just that: projections. So many variables can affect a player's point totals in a given season, but this at least provides us a rough road map.
Zykov's projection might be about right over a full season. Svechnikov's total is also probably in the wheelhouse: somewhere in the 40-50 point range. Though, if Svechnikov came in and blew the doors off like Patrik Laine did in his rookie season, that'd be cool, too.
The one projection that seems a bit off is Necas, but that makes sense given the extremely limited data from players who jump from Czech directly to the NHL. I'd expect Necas to be much closer to the 40-50 point range than 20-30, but we'll see.
This was a fun exercise! Hopefully it all made sense. And hopefully my math is correct. I'm sure someone will yell at me if it's not.
