Sounds very similar to Neal, as he was quickly passed by Lindholm and Frolik, although it is a smaller sample size.
I was more or less making a joke about fans arguing that their old player is worse lol
I think both players fill a need better on their new teams than their old ones, but don't think either player has much left in the tank.
For Neal I'm not really sure if it's even as dependant on what's left in his tank more than where McDavid can take him.
McDavid turned all of Kassian (on pace for 4 goals previously), Maroon (on pace for 6 goals with the Ducks previously), and Chiasson (on pace for 12 goals with the Caps) into 25 goal rate scorers.
Neal doesn't need to have the same amount in the tank to get to the same destination (20 goals) with McDavid.
Particularly on the Oilers where he's likely going to step right onto the top 6 and onto the top unit PP because none of the Oiler forwards really like to shoot the damn puck. They're all going to be looking to pass to him.
Hockey wise I don't think he can find a much better situation for him offensively. Three very good pass first centers, no real one-shot scorer on the wing to compete with. It's like not being the smoothest guy in the world but ending up in a town with a 2:1 female to male ratio and there being a few real good looking girls and all the guys are dweebs, lol.
