I don't think Gartner, and, say, Robitaille are very comparable:
1st/2nd-Team All Star
8 - Robitaille
0 - Gartner
100+ point seasons
4 - Robitaille (and another at 98)
1 - Gartner
Stanley Cup Finals' appearances
2 - Robitaille
0 - Gartner
(Incidentally, I think it's clear in retrospect that Gretzky's presence in L.A. actually lowered Robitaille's stats, since he got less ice-time. He got 111 points before Gretzky arrived, and only matched that again when Gretzky was injured.)
Gartner and Andreychuk are much more comparable, but, again, the difference is not in peak/prime but in consistency. Once Gartner couldn't score 30 goals anymore, he quit. Once Andreychuk couldn't, he played 11 more seasons.
I don't think Gartner was as good as Robitaille by any means. All I'm getting at is that this whole, "look at how many times the guy finished in the top whatever in scoring" thing can be used against other players as well.
It's only part of the criteria for evaluating players... or at least it should be.
When I said Robitaille is more comparable to Gartner than to Bure or Ovechkin, I meant that he consistently scored a lot but never led the League in goals and wasn't often a top five goal scorer. Bure led the NHL in goals a few times and Alex has done so many times.
There's always more to consider than just top five or top ten scoring finishes.
Here are Robitaille's best goal totals:
63, 53, 52, 46, 45, 45, 44, 44, 39, 37, 36, 30, 24, 23...
Here are Gartner's:
50, 49, 48, 48, 45, 45, 41, 40, 40, 38, 36, 35, 35, 34...
I prefer to use adjusted goals/point totals in comparison. I think doing so is more fair to Robitaille since he played through out the dead puck era as well as playing in the late 80s and the early to mid 90s.
Robitaille's best adjusted goal totals:
51, 45, 44, 44, 40, 40, 40, 40, 40, 39, 38, 35, 35, 26, 25
I those are very impressive as a set, but I'm not seeing a lot of particularly eye-popping numbers. There's a reason he didn't finish in the top three for goals in a season.
Gartner's best adjusted goal totals:
44, 40, 40, 38, 37, 37, 36, 35, 34, 33, 31, 30, 30, 30, 27
The season for season differences in adjusted goals between their corresponding best seasons are as follows:
7 goals in favor of Robitaille
5 goals in favor of Robitaille
4 goals in favor of Robitaille
6 goals in favor of Robitaille
3 goals in favor of Robitaille
3 goals in favor of Robitaille
4 goals in favor of Robitaille
5 goals in favor of Robitaille
6 goals in favor of Robitaille
6 goals in favor of Robitaille
7 goals in favor of Robitaille
5 goals in favor of Robitaille
5 goals in favor of Robitaille
5 goals in favor of Gartner
2 goals in favor of Gartner
The cumulative difference is 59 goals over 15 seasons or an average of just under four goals per season (3.93). That difference is enough to make Robitaille decidedly better during those 15 seasons, but he certainly isn't on an entirely different level.
Next, let's bring in Andreychuk...
Best goal totals:
54, 53, 41, 40, 38, 36, 36, 31, 30, 28, 28, 27, 25, 22, 21
Best adjusted goal totals:
48, 44, 38, 36, 34, 32, 30, 28, 28, 27, 25, 25, 25, 24, 23
The season for season differences in adjusted between his and Gartner's corresponding best seasons are as follows:
4 goals in favor of Andreychuk
4 goals in favor of Andreychuk
2 goals in favor of Gartner
2 goals in favor of Gartner
3 goals in favor of Gartner
5 goals in favor of Gartner
6 goals in favor of Gartner
7 goals in favor of Gartner
6 goals in favor of Gartner
6 goals in favor of Gartner
6 goals in favor of Gartner
5 goals in favor of Gartner
5 goals in favor of Gartner
6 goals in favor of Gartner
4 goals in favor of Gartner
The cumulative difference in goals between the two during these seasons is 55 goals or an average of 3.66 goals per season...
I think you have to look at the totality of their careers
in conjunction with their top five and top ten goal finishes in single seasons...
Top five finishes for goals:
Robitaille: 2
Gartner: 1
Andreychuk: 1
Top ten finishes for goals:
Robitaille: 9
Gartner: 5
Andreychuk: 2
Thus Gartner
is closer to Andreychuk than to Robitaille as a goal scorer but not by too much.
Robitaille is definitely the best of three.
Gartner is step down.
Andreychuk is a step below Gartner.
Of course, the biggest passenger of the three was Andreychuk; it's well known that he benefited heavily from Gilmour's two peak years in Toronto. He was also the worst skater and five on five of the three.
Some would draw the Hall of Fame line at Robitaille when considering the three, but I think it's fine to have Gartner in as well as a lower-tier induction. The door shuts on Andreychuk, however.
