I think the greats do both. Wayne was Wayne with or without Kurri being Kurri. He famously switches from being the GOAT goalscorer to the GOAT playmaker.
Mario elevated Rob Brown then elevates Jagr but his own production was the same. Then Jagr takes over and produces just as well on a depleted Pens team.
The point is that the GOATs do not see a significant jump in their own numbers when they get different linemates, but they bring up the level of their linemates.
Bedard seems like a player who maybe isn't quite the driver of offense like Wayne, Mario and Crosby but could be just as effective with good linemates. Unlike Crosby and McDavid, he could be the designated sniper on a line just as much as the primary playmaker,
I think he has a very high IQ which should help translate his CHL production into NHL production.
