Definition of daddy is simple, so that even you can understand it. If Dad is the coach, kid is on team or is getting playing time over other more deserving/better players. Breakers, Looney's, Rock all guilty....Hawks for sure.
If the Dad is the head coach and the son is getting more time, then I can see your point. Otherwise it sounds like the same whining heard all over this site "refs didn't like us", "they had a kid 6 months older", "coach has favorites".
