The level each of the big three(four with Mackinnon) needs to maintain to win accolades is much greater than during 2010-2016 because they're in direct competition with each other. They're just on a different level compared to the rest, sort of how Gretzky/Mario/Jagr were on a different level from everyone between 1981-2001. They're directly competing with each other, while Crosby/Ovi/Malkin from 2010-2016 never won the Art Ross over one another directly. Malkin wasn't challenged by Crosby/Ovi in 2012, Crosby wasn't challenged by Malkin/Ovi in 2014. Even Crosby in 2007 was challenged by Thornton, not Ovi or Malkin. McDavid/Drai/Kuch constantly winning the Ross over each other > Malkin, Crosby, Ovi winning Rosses over Getzlaf, Stamkos, Thornton(Ovi 08, Malkin 09 are exceptions).
Let's get the facts straight before comparing these guys to Wayne/Mario/Jagr. 2nd place in the Art Ross:
16/17 - Crosby/Kane (Kucherov 5th)
17/18 - Giroux (Kucherov 3rd)
18/19 - McDavid (Draisaitl 4th)
19/20 - McDavid (MacKinnon 5th)
20/21 - Draisatl (MacKinnon 8th)
21/22 - Huberdeau/Gaudreau (Draisaitl 4th)
22/23 - Draisatl (Kucherov T3rd)
23/24 - MacKinnon (McDavid 3rd)
24/25 - MacKinnon (Draisatil 3rd)
It really only has been the last two seasons that this quartet has stood out. Or rather that MacKinnon and Kucherov have put together full, peak seasons . Other than that, it's the McDavid factor; a generational talent who is putting up full (or close to full) seasons and likely dragging Draisaitl to 2nd place in a few of them.
There is no argument that injuries kept Crosby, Ovechkin and Malkin from winning more Rosses and that their peak level of play argubly surpasses Draisaitl, MacKinnon and Kucherov.
2011 to 2016 was also the DPE 2.0 (or a bit worse) where tight, defensive hockey brought the elite offensive players closer to the pack vs. the significantly higher scoring since 17/18.
