Yeah, it is funny.
How can somebody make such a claim? How could anyone know how Crosby would play in a mens league? Its impossible for anyone to know how he'll play, and handle the physicality UNTIL he plays in one.
Its pretty stupid imo to say "he would not dominate a mens league" with absolutely nothing to back up that claim.
Joe Sakic: 5'10 190
Markus Naslund: 5'10 195
Martin St Louis: 5'9 181
etc, etc, etc,
So tell me why Sidney Crosby, who weights a solid 185, with legs as thick as tree-trunks and all the talent in the world would have trouble in a mens league? It will be a bit of an adjustment for Sidney, but as he's shown in the past he is a very quick learner.
