Quoting: Spleenmaster1002
Don’t really see the point in this for the Jets. I don’t think Määttä is enough for the Jets to want to swap Laine and Debrincat.
I don’t think you’ve watched him this year. He’s noticeably better defensively and has been passing and setting up guys really well. He’s been using his body more and giving a lot more effort while forechecking and backchecking. He’s over a PPG and leading the Jets in points.
Points remain an EXTREMELY poor stat when quoted unmodified. Let's use Laine as an example to run through a few reasons. It'll be fun!
1. Points say precisely nothing about defense. This one's pretty self-explanatory: points only occur on goals scored by your team and are unmodified by goals, shots or chances against your team. In Laine's case, points miss that before this year he had yet to have had a year above replacement-level defensively, per EvolvingWild's GAR metric.
2. Points are EXTREMELY usage dependent. 6 of Laine's points came on the powerplay, which means a different coaching decision could nix 1/4 of his points production, without him doing anything different. And that's without factoring in how playing with elite teammates and seeing large amounts of icetime can bias the results as well. Laine's scoring rate at 5v5 (he has 13 5v5 points) could this year have produced: 15 (Schiefele's TOI), 11 (Roslovic's TOI), or 5 points (in 16 games, Bourque's TOI). All that changed between these scenarios is TOI, which player's can't directly control. NHL coaches are USUALLY smart about TOI allocation, but I doubt you could find someone who says they're perfect. No reason to punish a player for their role. And that's before accounting for teammate impacts (spoiler alert, they're pretty big).
3. Points are VERY luck-dependent. Shooting percentage is one of the most volatile stats in the NHL and forms a huge part of goal numbers, (and goals aren't even the least
predictive part of points, secondary assists have even more variance, to the point where they are essentially useless in skater evaluation). In Laine's case, the 20-point drop he experienced from 17-18 to 18-19 is entirely explained by his shooting percentage dropping by 6 percentage points (from 18% to 12%) and by his secondary assists falling from 14 to 3 (11 points right there). He wasn't really playing differently, but his points were way worse. Not really what you want from a stat.
Points work better when restricted to primary points (goals+primary assists) and used as a rate (e.g. P1/60). Even then, there's an argument to be made that advancements in regression models like EvolvingWild's RAPMs and Micah McCurdy's Magnus 2 more firmly measure individual offence by accounting for things like teammates, competition, score effects, etc. While using them in concert makes sense, it can lead to a tendency to double count offence, especially when using something like GAR, which is based off of the RAPMs.
Laine's defence has improved this year, but it's still not a strength of his game. He's mostly what he's always been, a great shooter that struggles to drive play at 5v5. That's arguably worth enough to make the deal make sense, since Laine's shot is one of if not the single best in the league, but still.
Stop using points. I don't care what Sportsnet says.
