All of a sudden the experienced lax coach becomes a 20 year old college kid coaching a team. Interesting. I don't recall seeing that anywhere before on this topic. But if I may, who's to say this young man hasn't learned the proper way to coach during his playing time. Even though he's 20 I'm sure he has more knowledge of the game than the "dad coach".
May I ask what organization you coach for so I can avoid it at all costs.
