If I was Pavel Bure, you might have already seen a comeback attempt.
I have only challenged two common claims made about McDavid: that he is a "generational" player, and that he is the fastest skater in the NHL. Both of these claims are based on hearsay.
I have always stated that McDavid would not be as dominant at the NHL level as so many people prior to 2015-16 stated he would be. I said that he would be a top-level player, but would never enter his own tier as Sidney Crosby has done.

Upon looking back at some of these articles, it appears that some of my observations about his game are weaknesses that he is aware of as well:

On the topic of his skating ability, people have made the claim that he is the fastest skater without any definitive evidence. Nobody who claims this has measured his speed; the claim is made from a hunch based on a visual observation.
McDavid is not the fastest player in the NHL. Anyone who believes that he is should provide footage.
Please stop trying to make this claim without any proof to support it. When you can not definitively answer the question and need to preface your statement with clauses such as "I would bet," it means that you are not certain. Offer proof before you make such claims.
I also did not make the claim that "Pavel Bure is the fastest skater of all time." Miles Wood might be faster. Bure had contemporaries who might have been faster -- maybe even his own teammate for two seasons, Russ Courtnall (I have not measured this).
Bure was certainly faster than McDavid is, though.
