When the Steelers took the field for Sunday's game, Terrible Towels littered M&T Bank Stadium.
With the Ravens entering Sunday's game with a 4-10 record and the Steelers coming in with a chance to punch their playoff ticket, it was no surprise that the enemy had infiltrated Baltimore's home.
But that's part of what made the Ravens' 20-17 series-sweeping victory so sweet – especially for the purple-clad fans who showed up. The win came with so many once eager and confident Steelers fans getting a front-row seat.
Despite the high number of intruders, Ravens fans were loud, roused by the team's early lead and never relenting.
"The fans were incredible," Head Coach John Harbaugh said afterwards.
"I'm proud of our fans, because we know it has been tough. … But for our fans to hang in there the way our team has hung in there, what a statement about Baltimore. What a statement about the kind of people we have here in this community. It's powerful."
Ravens fans were so loud that the Steelers burned two timeouts early and midway through the third quarter to avoid delay-of-game penalties. That cost them later in the game when Baltimore ran down the clock with a three-point lead.
"Our fans have been showing up all year," wide receiver Kamar Aiken said. "Our record wasn't a way of showing appreciation toward them, but they packed the house today, and they deserved that win more than anybody."
