Sorry. It’s a terrible argument when comparing players to Gaudreau who didn’t take typical career development paths.
It’s predictive value is close to zero.
It’s like people who misuse cherry picked stats around here to compare players.
It just goes to show how far some people will go to support their choice of their home teams player.
You can make a good argument for Marner but this isn’t it. Two equal players but one is younger.
The prediction in this case wasn't for what Gaudreau would become, it was for what Marner would become in relation to what Gaudreau was at the time of Marner's rookie season, and what Gaudreau really hasn't improved greatly from (it's a pretty good plateau, don't get me wrong). The predictive value in this case ended up being extremely high being that Marner (literally by your own admission in this post) has become a Gaudreau level player
Now, there's lots of evidence that Marner is the better player at this point in time including offensively, being that he's produced at a near identical rate with less opportunity and slightly inferior linemates while being a much superior two way player, but I wouldn't put them on different tiers either
I see Monahan as a 2C. Extremely one dimensional but he's excellent in that dimension. He really can't do much on his own. Meanwhile Tavares can very much create on his own - and has actually been known to make 3rd liners look like first liners.
I think he's a back end 1C in the context of where he ranks on the list of NHL centers, a #20-30 overall. And the Tavares comparison was a stylistic one, Tavares is better at everything but his best talent is the same as Monahan's best talent - finishing from within 20 feet
I would say it's only part of the consideration, not something to base an argument on. It's one thing when the younger player is projected to be much better, it's another when the established player is already roughly as good as the younger player is projected to be. This is the same argument that led to Finnish/Jets fans hilariously claiming Laine was going to be better than Ovechkin, despite having nowhere near the skating ability or overall offensive skillset. Evaluating skillsets is just as important, and I don't see Marner taking it to another level than where he's at now (which is similar to Gaudreau and could go either way) unless he somehow develops a killer shot. I would say being better earlier likely means a better career, as it would suggest a longer prime, but I think most signs point to them being comparable players through their primes
there's a risk vs reward if you were talking trade value for sure and I'd agree that its not a single factor consideration. The projection isn't from where Marner is now, it was from where Marner was as a rookie, and all signs pointed to the Gaudreau tier which has come true. I could see some improvement but I also wouldn't be surprised for him to stay around where he is either as a 85-100pt regular
When the Jets fans did that with Laine, they also conveniently overlooked his mid-high 20's shooting %, it's the same as what's happening with Pettersson right now. That stuff catches up and the luck evapourates, sometimes quickly like it did with Laine
