Parent coaches are always a problem. It can be the head coach or assistant coach but they can always have an impact as the roles of the players and the systems that are run. All of this can impact in who’s playing and touching the ball. Some clubs are worse than others.
It’s almost impossible to overcome this.

College coaches will many times walk up to the head coach and ask about players they see in games(even after 9/1). Some will then reach out to the player but others will have HC facilitate.
Coaches will connections can definitely get college coaches to watch and then it’s up to the players. BUT the coaches do have a major impact on all of that and the discussions before and afterwards. For this reason you should always be avoiding parent coaches.
