A1 secures possession of the ball with one knee in contact with the floor. May A1 assume a standing position without committing a traveling violation?
It depends on what A1 does. If A1 attempts to stand up while holding the ball, a traveling violation occurs. However, if A1 starts a dribble and then rises, no violation has occurred. Also, A1 could pass, try for goal or request a time-out from that position.
