What happened: Denver Broncos fans packed early Saturday flights to Arizona ahead of Sunday's road game against the Cardinals, according to reporter Troy Renck. The heavy turnout of orange and blue threatens to neutralize the home crowd noise for an Arizona team trying to build on its 18-16 win from Oct. 18.

Why it matters: Road fanbases travel in numbers when a roster proves it can win tight games, and Denver has earned that backing with a two-game winning streak following its 17-14 victory on Oct. 15. Sitting at 4-2 compared to Arizona's 2-4 mark, the Broncos have the momentum and crowd support to dictate the tempo on the road.
