James Harden is doing some crazy stuff this season. The former Sixth Man of the Year is nearly averaging an unfathomable 40 points per game. He just scored 60 points in a little more than 30 minutes of game action and hasn’t scored fewer than 25 points in a game since opening night. Defenses are now trying to trap him before halfcourt.

Is he the best scorer of this generation? Probably. Three straight scoring titles would cement that status.

But is he the best scorer ever? Well, that gets a little more complicated. We could simply list the best scoring seasons by points per game and leave it at that. But as you’ll see below, that would be short-sighted.

Why? Let’s start at the basics.

Harden is currently averaging 39.5 points per game. If it holds, that would rank third all-time on the scoring leaderboard for a season. The only name above him? Wilt Chamberlain, who of course sees your 40 points per game and raises you 50.

Case closed. Chamberlain is the best scorer ever, with the best scoring season ever, right?

Not so fast. Let’s zoom out and look at the top 20 scoring seasons in NBA history.

Notice anything odd? Hint: Look at the season column. Yeah, that’s a lot of of the 1960s. Eleven of the top 20 scoring seasons of all time came within an eight-year span. What’s up with that?

Chamberlain, Elgin Baylor and Rick Barry were incredible scorers, to be sure. But it has to be mentioned that they played in an era where teams regularly took over 100 shots per game. In an eight-team league playing at a crazy-fast pace, and in which Chamberlain was one of three 7-footers playing in the league, the NBA was ripe for an outlier season.

Though we didn’t have a complete picture in the box score (turnovers didn’t become an official stat until 1973-74), we can get a pretty good idea of how “fast” the league was in that season by using Basketball Reference’s best estimates. We find that Chamberlain’s team, the Philadelphia Warriors, played a whopping 131.1 possessions per game, the fastest of the eight teams. The slowest team, the Chicago Packers, played at 122.9 possessions per game. Even taken as a ballpark figure, that’s a Formula 1 race car compared to the speed of the modern era.

If you thought today’s pace-and-space era was fast, the back-and-forth NBA of the 1960’s leaves them in the dust. The fastest team this season, according to Basketball Reference tracking, is the Washington Wizards and they churn out 105.2 possessions per game. To put it in perspective, the slowest team in 1961-62 played almost 18 additional possessions per game than today’s fastest team.

That’s almost an entire quarter’s worth of extra hoops in which to rack up points. You might be asking yourself, “Well, what what happens when we take that same top 20 and adjust for pace?”

Good question! I tweaked the per-game numbers by normalizing it to a 100-possession environment. Players that played on a slow team (below 100 possessions per game) will get a boost and players that played on a fast team (above 100 possessions) will have their numbers fall back down to Earth a bit.

After making this adjustment, we get an entirely new leaderboard. Lakers fans, you might want to sit down for this one.

Holy, Kobe Bean Bryant! After adjusting for pace, Bryant’s 2005-06 campaign floats to the top of the list, up from his previous spot of 11th-best. It’s one thing to average 35.4 points per game, but it’s another to do it while playing at a snail’s pace. In Phil Jackson’s return to the Staples Center bench after a one-year hiatus, the Lakers barely cleared 90 possessions per game, over 40 fewer possessions per game than Chamberlain’s record-holding ‘61-62 campaign.

A comparison between Bryant’s 81-point game and Chamberlain’s 100-point game -- the two highest-scoring individual performances in NBA history -- further illustrates the difference in eras and playing styles. In Chamberlain’s infamous 100-point outing, the Warriors fired up 118 field goal attempts, which is 30 more scoring opportunities than the Lakers had when Bryant went for 81. (Chamberlain’s Warriors scored 169 points in that game, which was only the sixth-highest scoring game in NBA history at the time. Again: Pace.)

Bryant has always been considered one of the best scorers of all-time, but he happened to rule during the NBA’s Deadball Era, in which point totals slumped across the board. The 2004 Lakers scored 68 points in an entire Finals game for crying out loud. Under the terms of our exercise, Bryant would average an extra 4.4 points per game simply by adjusting to a pace of 100 possessions per game.

And Harden? He’s still near the top of the list. His current season is docked 1.8 points per game because the Houston Rockets have stepped on the accelerator this season with Russell Westbrook on board. The Rockets’ pace, according to Basketball Reference tracking, sits at 104.9 this season, up from 97.9 last season with Chris Paul running the point. By this measure, Harden’s season is almost a mirror image of last season’s scoring campaign.

More importantly, even through this new lens, Harden’s ‘19-20 scoring binge is still not superior to Chamberlain’s monster '61-62 season, but the gap is smaller. Once we put the era’s pace into context, Harden and Chamberlain are less than one point per game apart. If Harden’s season average surges to 40.3 points per game, that would put him on par with Chamberlain in adjusted points per game. (He’d need to finish at 40.6 and 40.8 raw points per game to catch Jordan and Bryant, respectively).

Is Harden having one of the best scoring seasons ever? Most definitely. It’s right up there with the legendary scorers in NBA history. If he starts regularly putting up 42 points a night in this environment, he’d have the best scoring season ever in my book -- better than Wilt’s 50.4 season -- but it’s hard to see Harden pulling that off. Then again, no one saw a Sixth Man of the Year averaging nearly 40 points per game, either.
