“Every single time I see that picture of me standing by myself, I feel embarrassed,” Villanueva said.
Both Villanueva and his teammate Ben Roethlisberger explained the circumstances that led to Villanueva standing alone. Roethlisberger said that a plan was in place for the team captains to stand together with Villanueva at the front of the tunnel for the national anthem. Villanueva made it to his spot, but the team captains couldn’t reach him before the anthem began. When it started to play, they stopped moving out of respect.
