In talking about peak age and age related drop in productivity, I assumed it was general knowledge. Or that you are capable of looking things up online.So you took the AHLe of EBEL players and then applied the NHLe of the given value? Does that sound even to you like great analysis? The NHLe is designed for one thing. It's designed to predict prospect performance in the NHL. It's tailored to that end. Take the OHL NHLe for example. It's about .3. An OHL player who scored 30 points in 60 games should score 13 points in the NHL. We both know that wouldn't happen. Ever. But the number takes into account players like say Kirby Dach, who go straight from the CHL to the NHL, so it's skewed towards the improvement curves of these higher end prospects. A 19 year old with .5 PPG would not even get 13 points in the NHL, the body of evidence suggests they likely wouldn't even get that many points in the AHL. But that's fine. Because that highlights the purpose of NHLe. NHLe is meant to project NHL prospects and their performance in the NHL. NHLe is a model meant to predict the performance of a guy like Kirby Dach, or a guy like Pierre Luc Dubois. It's not meant to predict the performance of just any 19 year old in the CHL. Furthermore, you're not doing principled statistical work. You haven't, to this point, mentioned the EBEL NHLe value. You haven't mentioned the ECHL NHLe value, and you haven't mentioned any of the NHLe values of the various D1 Conferences. Now you say you took the AHLe (more like the EBELe actually) of 65 players, with year skipping, with zero regards for the modalities surrounding such statistics, and you came up with a number that you're not providing. Neither have you mentioned the ECHL AHLe or the NCAA AHLe. So you say you're using statistics but the one thing you haven't provided is statistics. That's not principled application of statistics.
Actually, it's extremely pertinent and has many of the relevant modalities. Your only argument against is basically assertion, which can be dismissed by hitchen's razor. A 19 year old is more likely to receive prominent usage, as is a paid import who is both a financial asset and takes up points in the point cap system. A 16 year old is less likely to receive prominent usage, as is a rookie in say the ECHL, or an unpaid NCAA player who isn't an asset. Individuals exceptions may exist but with large numbers these truths will bear themselves out. The 19 year old and the paid asset will have more player time over a large sample than the 16 year old and the rookie. The same is true of improvement. You have to realize that no one comes straight from the NCAA to the EBEL. You obviously don't care because you have no problems with year skipping. The ones who come are selected by their drastic improvements. Players who have comes straight from the NCAA to the EBEL have typically not done well. The players who are in the NCAA at some point and eventually make it to the EBEL are those who show drastic improvements in the ECHL and/or the AHL or other European leagues such that they are hired as imports. That's a systematic bias. So even if it was the case that the improvement level for a player in the AHL or ECHL at a certain age was generally not very high, we are selecting in this case specifically players who did improve a lot, such that they went from having X stats in the NCAA to dominating the ECHL or doing well enough in the AHL. So this situation is actually far more like a 16 year old and a 19 year old in the OHL than even say a 26 year old and a 27 year old going from the KHL to the NHL, a more typical NHLe context.
Again, you just assert things, no evidence offered or required. The difference even between a 20 year old and a 23 year old is huge, much less a 25 year old. Even an excellent 20 year old will likely do better at 21, and then at 22, etc, until they reach a scoring plateau. So you could run the exact same experiment and find that the AHL was a stronger league when a kid is 20 than when he is 22. Again, exceptions exist. Some players regress. But over a large sample, the older versions of the same players will score more, and by your "model", the league will be proven weaker. And again, as with any import hiring, there is an intentional selection factor built in hiring players who improve the most. Just like KHL imports but to a lower scale, the players are hired most who show the most improvement to the point that they are strong candidates for hire. It would be so incredibly disingenuous if I took a player like Brian O'Neill and referenced his 2012-13 totals in the AHL and his KHL totals and said "the difference between a 20 year old, a 25 year old, and a 30 year old is negligible, so the AHL is stronger than the KHL." No it's not. Precisely because KHL teams hired him BECAUSE he improved. They hired him BECAUSE he was not the same player at 20 that he was at 25 or 30. If he had remained the same player that he was in 2012, they never would have hired him. The same is true of the EBEL. The EBEL hires NCAA players who played pro and improved in professional play such that they proved that they were capable of being valuable assets in the EBEL. So even if the general body of 20-25-30 year olds do not improve, which is not the case, but even if we granted this non-truth, it is not true of the sample size in question. Which is why we do not skip years. And by the way, NHLe statisticians do not skip years either. No NHL statistician is going over their team's prospect's NHLes from 3 years ago. They're crunching the recent numbers. Because only the most recent numbers reflect the improvement that has or has not taken place over time.
This is not a peer reviewed scientific journal. This isn't scientific research at all. It's a quick statistical comparison using the best tool available for us in cross-league comparison.
If usage rate for EBEL players is so skewed, it logically follows that they were so poor in ECHL/AHL, that they couldn't even land meaningful minutes or PP time. You're shooting yourself in the foot by using that as an argument. If they were so underused in North America and improved so much in EBEL, there should be droves of EBEL players in NHL and AHL. Where are they?
You claimed that EBEL imports improved drastically, but the truth is that they joined EBEL because they couldn't make it in North America. They weren't very good, so they went overseas. It's not the other way around.
NHLe is generally used in assessing prospects but it's a great tool in cross-league comparisons.
And I provided the evidence. The NHLes, the average production rate, number of players involved.
Your claim that EBEL imports somehow tend to magically improve in their mid-20s is absolute hogwash.
