If the best goal-scorer of all time is not in your top10 ever, there is a problem with how you rank players.
Ovechkin is as close to Bobby Hull as we will probably ever get; and Hull is as close to consensus #5 all-time as possible.
Even if you disagree with Hull being #5 all-time or still see light between Hull and Ovechkin, there is little argument to keep Ovechkin out of top10 all-time given how close it is between him and Hull.
What bugs me with people wanting to rank Ovechkin is the top 10 is that the only argument they seem to have is that he is a great (perhaps the greatest) goalscorer. That's the entire argument. It is a valid argument, but I think it is incomplete. Well, maybe not "incomplete" but I wonder how much it should influence the debate. Let's look at things in more depth.
Gretzky, Lemieux, Orr and Howe are the consensus top 4.
As you noted, discussion starts at 5.
Who are the "contenders" for 5 to 10? Hull, Richard, Béliveau, Lidstrom, Bourque, Hasek, Roy. Of course, then, there is the elephant in the room: Sidney Crosby. Many people consider him top 10, some will go as far as to say he is on track to the consensus 5.
To me. Béliveau is easily ahead of Ovechkin. Bourque, Lidstrom, Hasek and Roy are difficult to compare to Ovechkin because they play different positions. Hull and Richard are primarly goal scorers, so they can be a good comparaison. I feel like both were more complete players than Ovechkin (maybe not Richard)... at least post 2010-2011 Ovechkin.
Now, as I said before, the elephant in the room: Ovechkin's contemporary and main rival: Sidney Crosby.
One thing nobody will argue: Alexander Ovechkin is a better goalscorer than Sidney Crosby. During their entire careers, Crosby beat him in GPG only once (and it was a partial season for Sid). Career GPG are 0.61 vs 0.47. Over 82 games, it is 50 goals vs 39 goals for a 28% advantage for Ovechkin. I mean, it is pretty clear. No argument here. So, if someone wants to bring trophy counting, I'll just say that well, he has 9 Rockets, he is clearly the best goal scorer, duh. It is still super impressive and that's why Ovechkin at least deserves to be in the discussion for top 10.
If we look at overall offensive production.
Crosby's PPG is 1.28. Over 82 games, that's 105 points
Ovechkin's PPG is 1.11. Over 82 that's 91 points
Crosby wins by 15.4%
Over their careers, Ovechkin had the better PPG 4 times (all within their first 5 years) and Crosby had the better PPG 12 times, including the last 11 years.
Crosby never had a year under PPG. Ovechkin has 4 (5 including this one, but that's not fair, he is like 1 point behind pace).
Crosby seems to be winning by a lot, but, to me, it is incomplete. We need to look at things more closely. Peak Ovechkin (his first 5 years) was a different animal. Let's compare their first 5 years and then the other years (a point in time people like to refer as "Ovechkin declining" - his PPG declined, but his goalscoring remained fairly high: 0.68 vs 0.58, small decline, but we are talking over 11 years including like 1 or 2 outlier years)
First 5 years
Crosby's PPG is 1.36. Over 82 games, that's 112 points.
Ovechkin's PPG is 1.34. Over 82 games, that's 110 points.
Crosby wins by 1.8%.
For the first 5 years, if you want to argue that Ovechkin was a better player because he beat Crosby significantly while their PPG was nearly identical. I cannot put much of a fight. Heck, despite winning the overall PPG, Crosby lost 4 years out of 5.
Now, let's look at the last 11 years...
Last 11 years
Crosby's PPG is 1.23. Over 82 games, it is around 101 points.
Ovechkin's PPG is 0.99 (let's give him 1). Over 82 games, that's 82 points.
Crosby wins by 23%.
Productivity wise, it is not even close. Ovechkin is still the best goalscorer by about 10 goals/82 games (27%), but Crosby is the better point producer by 20 points/82 games (25%). Does a 27% in goal scoring erases a 25% PPG advantage? And we are not even talking about the rest of their games here nor are we talking about their team/international achievements, just pure offensive production. I think Crosby, for the last 11 years, has easily been the better players.
If we look at the playoffs, you can see the same dynamic.
Both were neck and neck during their first 5 years (1.32 for Crosby, 1.33 Ovechkin). Crosby had two finals, 1 cup and 2 CS worthy runs. Ovechkin never got out of the second round. So from a legacy standpoint, Sid at the better first 5 playoffs, but individually, Ovechkin was just as good.
Next 11 years, Crosby has 107 points in 106 games for 1.009 PPG. Ovechkin has 81 in 99 for 0.81 PPG. Over 82 games, it is 92 to 77. 19.4% win for Crosby. Legacy wise, Crosby played in 2 finals, won two cups and won two CS. Ovechkin played in 1 final, won 1 cup and 1 CS. Crosby wins from a productivity and legacy standpoint. Productivity wise, it is not even that close.
So, to me based on overall productivity, playoff productivity, playoff legacy AND having been the most productive player for 11 straight years, I put Crosby ahead of Ovechkin career-wise. I do not think the gap is that big and I DO think Ovechkin's goalscoring does close it a little - heck, I'd even have to acknowledge that Ovechkin might have peaked a little higher or, at least, he DID play during his entire peak and produce results. However, when you look at complete legacies, it is obvious is who ahead of who from an historical perspective.
If you cannot put Ovechkin before Crosby or Béliveau. Ovechkin is at best 7th all-time. Then, to decide if he is top 10, you need to compare him to Hull and Richard. You also have to figure out a way to determine if his impact was greater than guys like Shore, Lidstrom, Bourque, Roy and Hasek. Basically, you can have him anywhere from 7 to like 15. So, despite being the best goalscorer of all time, he COULD be as low as 15. Maybe even lower depending on the rankings. He could be as high as 7th though, and that's fair. Maybe even 5th if the argument is really compelling, but I would strongly disagree.
I mean, that's only my opinion and it is worth what it is worth, but I do not see anything "wrong" with it. I do not think Ovechkin being top 10 is a slam dunk strictly because he is the best goal scorer ever. He is certainly in the argument though and I would respect someone putting him as high as 5th. I'd disagree, but it would not be a stupid take.
