The grinder comment is based on his statistical finishes. I'm actually convinced that Canucks fans have no idea where his scoring finishes were relative to the league. Having not watched him play, I'm genuinely baffled at what it was that made Linden so highly regarded.
This is where Linden was in league scoring from 1989 to 1997 (I'm going off where NHL.com is listing him vs counting ties out of laziness):
1988-89:
181st (59 points in 80 games; Linden finished just above Russ Courtnall in the scoring race because he had one more goal. David Volek is listed above because he scored 59 points in 77 games)
1989-90:
112th (51 points in 73 games, just below Tom Kurvers with 52 in 71 and just above Dave McLlwain who had 51 points in 80 games)
1990-91:
42nd (70 points in 80 games, just below Michal Pivonka with 70 in 79, and above Kirk Muller with 70 in 80, but with 16 goals to TL's 33)
1991-92:
44th (75 points in 80 games, tied in scoring with Brian Bellows and above Vladimir Ruzicka who had 75 in 77)
1992-93:
77th (72 points in 84 games, just below Jimmy Carson who had 73 in 86 and for some reason listed above Dimitri Kvartalnov on NHL.com, who had 72 points in 73 games)
1993-94:
80th (61 points in 84 games, just below Dave Gagner who had an identical statline in 8 less games, and right above Scott Mellanby with 60 points in 80 games)
1994-95:
44th (40 points in 48 games - tied with Vincent Damphousse, just above Stephane Richer's 39 in 45)
1995-96:
35th (the "near PPG" season - Trev's highest ever scoring finish. 80 points in 82 games. Comparable to Petr Bondra who had 80 in 67 and Brian Bradley who had 79 in 75. Filtering for players with more than 25 games, Linden finished 45th in points per game)
1996-97:
140th (an injury filled season of 40 points in 49 games which obviously hurts the scoring finish. 50th in PPG, along with Andrew Cassels and Geoff Sanderson)
Like... he never even once came close to cracking a top-20 point finish. I'm too lazy to go back and confirm, but I don't think with a career high of 33 goals (three separate times) that he ever cracked the top-20 in goals either.
Now look at this:
NHL Stats
Linden was consistently very good for a very long time; definitely gotta give him that. And Naslund's fall from the top was rough. But at their
best, I just don't really see a comparison from looking at the stats. Linden had one 5th place Selke finish from what I can find. He'd need like, 3 wins to make up the offensive difference between the two.
