Yes, let's call a player who never scored more than 18 points per game in his entire career the 3rd best player of all time.
In fact, only two years did he ever score 20 ppg in the playoffs.
By the numbers:
56-57: Russell was the FOURTH option on offense for the team, scoring 13.9 ppg in the playoffs. THREE teammates scored over 20ppg.
57-58: Russell is the FIFTH option in the playoffs this season, despite his avg increasing to 15.6 ppg. All FOUR other starters scored >19 PPG. Celtics lose the championship to the St. Louis Hawks.
58-59: Once again, Russell is the least potent offensive player of all starters, FIFTH in PPG. And again, averages 15.5 PPG in the playoffs.
59-60: Russell is the 2nd option this year (18.5ppg) behind Tommy Heinsohn (21.8ppg). Russell manages the stellar EFG% of 45.6 despite being a big man on an incredibly loaded Celtics team.
60-61: Russell is again the 2nd option behind Heinsohn. However, per 36 minutes, Russell is outscored by SIX Celtics in the playoffs.
61-62: The FIRST SEASON Russell is the go-to on offense. He has 4 rings at this point and averages 22.4ppg. However, his scoring per 36 is still behind 5 other Celtic players, at a relatively pedestrian 16.8.
62-63: Sam Jones becomes more a part of the offense and again Russell drops, not just to 2nd, but to the 3rd option on the team for the playoff run. He averages just a shade over 20ppg. Russell's EFG% is 45.3.
63-64: Russell drops to the FOURTH option on the Celtics in the playoffs, at a measly 13.1ppg, with an EFG% in Mamba territory at 35.6%. This would put him as the least effective big on offense in the NBA today if he were playing. For comparison, Sam Jones has an EFG% of over 50% on the post-season. At this point, Russell has 7 rings. He has been the primary scorer for his team ONE time. He has been the tertiary scorer, or lower, 5 times out of his 8 NBA seasons.
64-65: Russell is again the 3rd highest scorer in the post-season. Jones is a force, scoring 28.6ppg ahead of Russell (16.5) and Havlicek (18.5). Per 36, Russell is the 7th highest scorer on the team, ahead of ONLY KC Jones in players who see major minutes for the Celtics, who win another le.
65-66: Russell is 3rd again, at 19.1ppg. He is still far down the list of per36.
66-67: Russell is the 5th option on offense with 10.6ppg, and a paltry 8.8p per 36. Despite his lightened load, he shoots an eFG% of 36. 36%!
67-68: Russell avgs 14 ppg as the 4th option. Cs still win the le.
68-69: Russell averages 10.8ppg with an eFG that is eclipsed by 4 teammates. Yet the Cs, again, still win the le.
Please note that all of the above are playoff stats. If you look at Russell's regular season stats, they look even worse most seasons.
So yeah. Results matter. Russell's results come from being on the most stacked team in the history of professional American sports, and that is not even debatable.
It is pretty damn easy to be "the ultimate winner" when your teammates are all Hall of Famers and the league is scattered with talent that wouldn't even make a top 25 college team in the modern era. Russell's results are that he was the leading scorer on his team ONE time in the entire 11 le run. One of the greatest defenders of all-time, unquestionably. One of the best big men of his era, no doubt. And his rings do count for something. But, as always, rings are massively overrated because they only ascribe individual success to a team sport. Russell WAS very much like Dennis Rodman -- a dominant defensive player that could scarcely dribble the ball or score effectively on offense.
If anything, looking at advanced stats probably places Russell much lower, in the ~15 range, rather than higher. He was incredibly one dimensional and not a good offensive player much of his career even when surrounded by 4-6 of the 8 best players in the league.
