yeah they are cumulative stats... you are in the league longer, you play more games, and you get more points. some of the players have like 200+ less gp so far in their prime years and aren't going to have totals as high, or some have made vast improvements from when they were years ago. Huberdeau is right behind him too....... is anyone ranking Huberdeau similarly offensively to scheifele in that list today/going into next year?
Elias Pettersson is 46th in that list, and just finished 10th, 5th, 26th in scoring the last-3 seasons vs scheifele 23rd, 31st & 23rd. do you think EP is inferior offensively going into next season b/c scheifele's totals since 2016 are better? or JT Miller for example; is 11th on that list last 3 seasons he's 5th, 16th & 5th in center scoring.
what's more reflective of his current level of play-2016 stats, or an average of some sort of recent years? & then consider the offensive scale of the league has widened drastically where there's more players achieving high numbers. for instance there were 32 PPG players last season, vs 8 PPG players in 2016 - which he was a part of obviously why folks thought he was a top-10 C during that time frame being 1/8 PPG players. now PPG is a bit more watered down (still v impressive of course). at this stage of his career which is what most are concerned about going into next year as opposed to a career reflection, he's closer to a mid-lower end 1C in terms of offensive production at least & not sure how he'd rank in all-around play. Don't think anyone is saying he is bad, but the a lot of Centers have caught up to him or surpassed him.
going back to OP that Eyeseeing posted, offensively at least he hasn't been top-20 for a few years now. and in all-around play
