You guys sure are coming.down hard on dads. Why not just make a state wide rule that all coaches be sterilized so the issue doesn't come up?! Don't get me wrong, there are some really bad daddy ballers out there BUT there are some really good coaches that have become better because of their dd's. I will tell you now, most class A or B teams coached by dad's are better coached than the majority of high schools.
Back to the OP, limit the number of asst coaches so you don't end up with a "hey Sally's dad is in there, why can't be?" argument. Let the head coach and AD decide which assistant parents they want in the dugout. If you guys are dead set on making a rule then have it where maybe only head coaches or asst coaches of current teams can be in the dugout with the AD having final say as to who can and can't.
