Was this attempt to get up... I dont think so.

Did this give them advantage? I think so?

Is their right butt/hip considered a pivot like foot and changing that pivot to the left butt/hip considered changing pivots?

I wish the rule book made this clearer because half the referees I see call nothing and half call a travel.

My friend says roll over means rolling as 180 degree barrel roll. I see this as more advantage partially rolling away from a defender who comes to tie up the ball.

I want the opinions here with any reasoning why that I can use on my partners/coaches to make me a better referee. I see this play happen I want to be more confident inside and out when I make my decision.

Thanks in advance.

Assume it is not a travel unless you can find something definitive in the rule book that states this action is a travel.
