I didn't play hockey, so I could be wrong.
The best kids are possibly going to be the most involved. As a C, you take Face-offs, you are engaged in all 3 zones.
I mean that the best players, growing up, possibly will play this position.
If it is "detrimental" to the person, they may be moved to the wing.
For some, the extra responsibilities might make their offensive game suffer.
The consensus is usually that you need a #1 center, #1 defensemen and a top goalie.
Hockey is about scoring.. so if the winger scores more, down the line, he may be more helpful to the team.
