Perhaps you can be the first person in the history of HFBoards to show that Crosby actually elevates teammates more than McDavid or any other all time great.
This is one of the many things that gets said for Crosby that there isn't a scintilla of evidence for.
It directly disputes what you said. I guess I'll tie the points together a little more explicitly.
You claimed a prime Crosby would never miss the playoffs.
A prime Lemieux missed the playoffs. In fact it was more difficult to miss the playoffs back then.
Prime Lemieux >>> Prime Crosby.
Therefore a prime Crosby could certainly miss the playoffs.
(BTW this is true for all players because hockey is very much a team sport and it takes much more to win than any 1 player can provide).
If you want me to quantify it, I cannot. It's just an eye test concept of watching Crosby play with less heralded guys like Kunitz for a longer period of time and making do. Eye tests can be wrong. However, you saying there's no evidence Crosby elevates his teammates more than the other greats, and I think the opposite is true as well. There is no evidence he doesn't elevate his teammates less either.
Like it was mentioned, I believe the two are relatively on par. The difference between the two when I mention it is preference to keep elevating others vs the ability to elevate others. Again, eye test based on the path the guys he played with took to reach the NHL.
McDavid has been able to do the same with guys like Yakupov, Pulujarvi and Chiasson. I never meant one is significantly more capable of elevating than the other. I said that based on track records of the rosters so far, Crosby playing with less heralded guys has been a constant vs McDavid being on a line with the best the roster has to offer and certain guys are pulled off his line after a while.
This creates an assumption is that McDavid prefers playing without anchors on his line and doesn't prefer elevating "nobodies". IIRC, McDavid has played a lot with guys drafted in the top 5 (Hall, RNH, Pulujarvi, Yakupov, Draisaitl etc.), even if some of the others were nobodies and busts. But Crosby doesn't seem to care about that and is more willing to invest in longer term relationships with his wingers, even if they are unheralded (Guentzel, Kunitz, Dupuis, Sheary etc. mostly undrafted guys).
Again, it is merely an assumption. A deduction purely based on eye test and the stories of the players they've played with.
