Talanoa Hufanga looked primed to play heavy run support.
The Broncos safety lined up near the line of scrimmage on first-and-10 in the second quarter last week against Houston.
To his left were inside linebackers Alex Singleton and Dre Greenlaw.
Denver put eight in the box against a run look from the Texans, who had back-up quarterback Davis Mills in the game.
Hufanga started to rotate out toward the middle of the field just before the snap.
Then his instincts kicked in.
Mills playfaked to running back Woody Marks. Singleton and Greenlaw both flowed hard toward the run action.
