COMPLETED OR INTERCEPTED PASS
A player who makes a catch may advance the ball. A forward pass is complete (by the offense) or intercepted (by the defense) in the field of play, at the sideline, or in the end zone if a player, who is inbounds:
a. secures control of the ball in his hands or arms prior to the ball touching the ground; and
b. touches the ground inbounds with both feet or with any part of his body other than his hands; and
c. after (a) and (b) have been fulfilled, performs any act common to the game (e.g., tuck the ball away, extend it forward, take an additional step, turn upfield, or avoid or ward off an opponent), or he maintains control of the ball long enough to do so.
------
Chase secured the ball in his hands. The ball didn't touch the ground. He performed multiple "common acts to the game" - he took a third step, he turned upfield, and he avoided his opponent. The "maintains control of the ball long enough to do so" is an either/or situation - he must not make a common act AND maintain control, he must do one or the other.
