So, the upshot of two long posts with a lot of numbers
Is Ovechkin's 07/08 season among the very best goalscoring campaigns in history?
Is Ovechkin's 07/08 season among the very best goalscoring campaigns in history?
There are five goal-scoring seasons in the whole history that are clearly better than Ovechkin's 2007-08 (to the tune of "what if Ovechkin scored 75 goals")
Howe 1952/53, Gretzky 1981/82, Gretzky 1983/84, Lemieux 1988/89, Brett Hull 1990/91
Then there is a second group of seasons where Ovechkin's 2007/08 lands: Richard 1944/45, Howe 1950/51, Howe 1951/52, Bobby Hull 1965/66, Bobby Hull 1966/67, Esposito 1970/71, Bossy 1978/79, Brett Hull 1991/92, Bure 1999/2000, Stamkos 2011/12 - and actually Ovechkin 2014/15. So that's 12 seasons in total, and surely one can make an argument that Ovechkin's 2007/08 is the best of the dozen (Ovechkin was on a bubble team, his center was old Fedorov or rookie Backstrom, Ovechkin dragged his team into the playoffs and his goals came when the team needed it the most and when the opposition was most motivated - or we can start dissecting the numbers, as many posts in this thread are doing).
In short, Ovechkin peaked as a goal-scorer behind the Big4 and Brett Hull, but on par with (or slightly better than) Bobby Hull, Richard, Esposito, Bossy, Bure, Stamkos.
Ovechkin's 2007/08 is not the top5 goal-scoring season ever, but can well be top10 ever.
What makes Ovechkin the best goalscorer ever is not his peak, but his ability to stay close to the peak level for more than a decade. Ovechkin peaked at 63% lead over #10 in goals, but he also has 8 seasons with 40%+ lead over #10 in goals, which, adjusting for the era, is at least 2 seasons more than anyone else in history. How does a lead of 40%+ over #10 look? Well, recall Ovechkin's 2008/09 or 2009/10, or recall Lemieux' 69-goal season. That's how this lead looks.
