1) RE: The bolded, I'd be far, far more concerned if Eichel was all passionless "aw shucks we tried hard" puppies and rainbows shit Phil Housley spouted ad nauseum.
2) RE: Leadership. Eichel was done for the season after the 7th loss of the streak. Do you think the Sabres would have lost 18 in a row if Eichel had continued to play? Do you think they would have lost 7, or 18, or pick a number, in a row if he had been healthy?
3) Why the mild obsession with # of 40-goal seasons, or goals scored by the player? Do the goals scored by teammates whom both Eichel and Matthews assisted on not count toward the game results?
4) Their career stats are hardly that different. Throw out Eichel's first season and count the seasons they were in the league together, and Eichel's PPG is 1.02 vs. Matthews 1.05.
5) Count the seasons they played the same schedule against the same teams: 273 games 281 points = 1.03 PPG;
282 games 285 points = 1.01 PPG. Does it matter which stat line is whose?
6) Without going to game-by-game logs (i.e., any errors in approximations are likely beyond the decimal point), here are their individual % goal share of their team goals scored, by year in the league:
1st 12% 16%
2nd 16% 16%
3rd 15% 16%
4th 13% 20%
5th 19% 24%
7) Marcel Dionne played 18 years in the NHL. He routinely finished in the top-handful of scoring leaders, won the Art Ross, Lester Pearson, Lady Byng, was a repeat 1st or 2nd team All-Star at season's end (don't know if they still do those teams).
Dionne was #2 or #3 in all-time scoring behind Howe and Phil Esposito for 5 years before his final season.
In his final season, Gretzky passed him to put him back in #3 all-time.
In 18 seasons, Dionne's teams made the playoffs only 9 years for a total of 49 games. He never made the playoffs until he was traded from the Wings to the Kings.
Teammates/Talent and coaching/style of play matter. They mattered for Marcel Dionne, and they matter for Eichel and Matthews. In the season ending year below, here is the goals-for and goals-against differential per game for the two teams (TOR minus BUF).
Year GFD GAD TOT
2017 0.61 0.06 0.55
2018 0.95 -0.59 1.54
2019 0.73 -0.24 0.98
2020 0.57 0.14 0.43
2021 0.87 -1.09 1.96
i.e., in 2021 TOR goal differential is near 2 full goals better than BUF, but none of the numbers above are adjusted for when Eichel or Matthews were out injured.
8) My conclusions?
Each is the most important offensive talent on their respective teams.
Matthews has been helped by his better surrounding talent, coaches, and team playing style / system more than Eichel has been helped by his.
Anyone arguing one better than the other needs a time machine to put the opposite player on the opposing team for those same seasons and then watch the results.
