in order to re-establish himself as a runner, he has to do one of the following:
- be capable of avoiding or warding off impending contact of an opponent NO
- tuck the ball away NO
- turn up field NO
- take additional steps NO
he never re-established himself as a runner, so down by contact doesn't come into play. instead, note #1 comes into play, which references "
players going to the ground in the process of attempting to secure possession of a loose ball":
in this situation, he "
must maintain control of the ball until after his initial contact with the ground"--he clearly doesn't do that.
