Why call traveling? It's the NBE.

Are you sure?

DRIBBLE – LEGAL AND ILLEGAL MOVEMENT
4.15 COMMENT: It is not possible for a player to travel during a dribble. A player
is not dribbling while slapping the ball during a jump, when a pass rebounds
from his/her hand, when he/she fumbles, or when he/she bats a rebound or pass
away from other players who are attempting to get it. The player is not in control
under these conditions. It is a dribble when a player stands still and bounces the
ball. It is not a dribble when a player stands still and holds the ball and touches
it to the floor once or more than once.

Granted he wasn't standing, but was Rondo holding the ball while touching it to the floor?

We know that doesn't constitute a dribble, so if the official deems him to be holding the ball, then getting up would be illegal.
