What about Paul Maclean, Thomas Steen, Randy Carlyle, and Laurie Boschman? A bit before my time, but still.
Paul Maclean(who I liked as a kid) was a mediocre garbage man. Tough and battled in front of the net. He belonged in the league but he was a product of Hawerchuk(and Yzerman for a season).
Steen was a good player, who had even worse linemates than Hawerchuk. He had Doug Smail stapled to him for a decade(Smail was an ok player, but probably would have been a 4th liner on most teams). That being said Steen was a center, and only played with Hawerchuk on the PP.
Boschman was a defensive player/pest. Not an offensive guy at all. Any high point seasons from him were purely because the jets didn't have other options. Hawerchuk's other linemates were mostly Brian Mullen, and later McBain and Iain Duncan briefly.
Carlyle was an ok puck mover but he was older by that time. I would say he benefited from Hawerchuk more than the other way around. Dave Ellett and Babych were better puck movers for the jets around that time.
The only comparable production without supporting talent to Hawerchuk, was Yzerman in mid-late 80s. Even then, I would say Yzerman achieved less(except for 1989) with more help. Which isn't me taking a shot at Yzerman, I think Hawerchuk was that underrated.
