Tony Romo
Some Dallas fans think that the franchise held onto Romo for too long. He didn’t always demonstrate the technical ability of an elite quarterback but there’s no questioning his heart. Romo famously completed one game against the Niners with a broken rib and a punctured lung. This came after a hard Ahmad Brooks hit.

Romo took painkillers and waited for them to work their magic. Then he returned to the field for the fourth quarter and it was like there was nothing wrong with him. NFL stars are a special type of human because they endure physical brutality that most of us couldn’t dream of (via NBC Sports).
