Bailey Knaub was diagnosed with an autoimmune disease when she was 7. In the 10 or so years since she has undergone 73 surgeries and had to have one of her lungs removed.
She got to meet her hero Tim Tebow before the Steelers/Broncos playoff game. He even mentioned her by name in the press conference afterwards.
As a Steelers fan, it hurts to be reminded of the game- but this was really nice of him.
