When these games start out physical, the refs need to huddle the players and tell them to commence or get called for a foul.
Once the refs allow it to go on, it's hard to go back.
I hate seeng kids get in early foul trouble, which can change the outcome of a game.
But a foul is a foul. And good refs will take control of the game when it get's out of hand.
If a player knows he can't get away with a foul, they adjust and so will coach's.
The flow of the game becomes much better after the unnecessary physicality is called for a foul.
Playing physical is apart of the game.
But in some games it needs to be cleaned up early by the refs
