Thank you for sharing that you are staying with Roy. Like that has any current revelance to the fact he's coaching for free so he can strategically set up plays so every pass is directed to his kid. Your kid must not care about that or you must be a really good friend of his. Either way I think parents moved on from it.
And yes every team has parents that are loud. And make no mistake about you may be cheering for the whole team, but Roy is telling the team to pass to his kid. He's cheering for his kid and if it came down to your kid or his, well it would be his. Congratulations on your decision!!!
