Direction of Play

I need some advice from you seasoned officials out there. I am relatively new, with about 50 games under my belt this year, yet still, on occasion, struggle with remembering the direction the teams are going when making quick out of bounds calls. I remember a post here when I first started where others mentioned this as well. Early on, I would yell, "off blue, red ball" if confused without pointing in the direction of play, but I know this is not proper and can be confusing for the younger players.

I have gotten better with experience, yet on occasion still struggle, especially if I've done several back to back games and lose a little concentration. I will glance at the benches briefly to remind myself before making the call (the proper technique of raising your hand to signal to stop the clock gives you that extra time). Anyone have any pointers in this area? Other than that, I feel very comfortable on the floor and feel good about my overall technique and rules knowledge. My confidence will grow if I can improve in this area.

thanks
