Rough play question

[Firemikeb]

This is my first year and I have done quite a few adult rec league games and now am doing AAU tournaments. My question for you more experience folks is-- I seem to have more trouble calling games where the level of play might be a little lower but the players are very aggressive with lots of tie-ups and rough play. In those games it seems there are calls that can be made on every posession but then you would just be marching back and forth between free throw lines. Or do you find that if you just start calling the games really tight the players back off. Thanks, Mike
