If you watched tournament games where every 50/50 call went to the home team, would you sign up for that tournament? Or would you find a better use for your time?
Not everyone does it. Most companies would fire a hiring manager who brought in his friends without disclosing the connection and recusing himself.
AYSO has been able to set up standards for player selection that mostly keep coaches and dads from favoring their own. So have most symphonies. It is not that hard.
If YNT still allows coaches to bring along their own players, that's good to know. It means USSF does not want to set up an unbiased review process.
However, if that's the case, I won't advise kids to try out. If YNT gives every 50/50 to the home team, there are other games to play.
