I dont know. Without injuries I those seasons between 2011-2013 he was clearly pacing to have an unreal peak. But since he got injured, we are left with his 120 point season. Which is still a clear peak imo
He's certainly the poster boy for consistency, so if its anyone it probably is him. Problem is, I think OV had a better prime, so its hard for me to say.
In this thread, people are saying McDavids hasnt dominated to the effect of Jagr because he beat Giroux by 6 points etc. But if he keeps going on like that, then he could have 5/7 Art Ross and never have truly "dominated" his peers in one season.
Personally I dont think it will happen, hes too explosive and one year everything will just go right, then he will have 126 points or something ridiculous. Right now though, McDavid wins awards because hes winning the long game, he gets 3 points every 2 nights for the whole season instead of streaking like Laine or others. That's not evidence of a peak, so all we can really do is speculate.
Edit - this will hurt his all time status with some posters though. He could be known as a guy who barely won 6 art ross because his competition was weak and his peak wasnt even great
