Let's talk about floor positioning on the fastbreak...

If the ball is opposite you in your primary as trail, you should be out on the court pretty far. If a turnover occurs, you can usually beat it down court and see the entire play. If you can't get there, you can use your "C" position to get the best angle.

If the ball if more on your side, you should be close to the sideline. Then, you need to trail the play, again similar to a "C".

I'm like you. I can beat most any of them down the court. But, I have to remember that my main job is to referee the play and get the best angle to do that.
