The general consensus is that when a player is on the floor they can get up if they are on their knees. If they are lying on the ground they cannot get up and play on because it is regarded as a travelling violation.

In regards to rolling around on the floor - if the player is backside down on the ground, they can move the ball from the left side to the right side (visa-versa), they can throw/pass the ball away, as long as they don't roll over on the ball etc. ie. get a distinct advantage, if an advantage is received I tend to ping it and call the travel.

I think the rule used to be interpreted such that a player could not slide across the floor with the ball – they can now do this as long as they aren’t sliding into other players (a foul), or get up after a slide (a travel).
