Usually this is all wishful thinking from the Dads of the big, slow players. In the end it is skating. Skating, skating, skating that separates players. If big blubber boy can't keep up to the pace of the game he will quickly fade away. Sad but true.
The guy is right.
You can be a very good skater and small and still play; You can be a very good skater and large and still play; You can not be a below average skater and small and play; You can not be a below average skater and large and play.
The big slow kids become a total non-factor.
