He is vastly underrated here!
Imagine a player who wins the Hart in his rookie season? Imagine a player who is also so talented that he ties for the league lead in points in his rookie season? Imagine a player who, in his second season, smashes the all time record for points in a season (164) while the second best player on his team only gets 75 points (Kurri)? Of course, I could go on and on but don’t have time.
The obvious fact is that a player with such mind bending talent possesses skills that no one ever possessed before or since:the ability to know where all 10 players are simultaneously while anticipating farther ahead in time than anyone before or since while processing plays and systems faster than any mind has before or since.
I think we can all agree that these skills would allow such a player to dominate an era! Why? Because the power of the human mind, when fully harnessed, will consistently prove superior to physical tools such as speed, size and strength.
