Three things to watch in a single play

[MathReferee]

1. Travel. I have to admit though that I was more focused at looking at the travel at the end of the drive. The initial dribble looks like a travel as his pivot foot is lifted prior to the dribble, but as he ends, it appears that he jumps off his left foot, then obviously lands right, left. Though it is difficult to tell if he is already airborne when he ends his dribble.
2. No call here.
3. Does not look like much contact from this camera angle. "C" had the opportunity at the best look at it.

More importantly, what does everyone think of the officials positioning in relation to the play? This is my number one priority this summer, so something I want to learn more about from the experts in these situations. It appears to me as if T could close down on the rebounding action, and C could do the same (maybe getting a better look at the rebound??).
