What happened: Denver opened the second half with drives of four, three, three, five and three plays, all ending in punts. The stretch totaled 24 yards of offense while the game remained in progress.

Why it matters: The empty possessions keep pressure on Denver's defense with the margin still narrow. Continued stalls shrink the margin for error the rest of the way.

What to watch: Watch whether Denver produces a sustained drive on its next possession to change field position.
