Mario Lemieux
It’s insane that Lemieux is arguably the greatest hockey player ever because he battled incredible odds. There’s no doubting his indisputable talent but his body was his worst enemy. A back injury caused him severe problems for most of his career but he still performed at an elite level (via The Hockey Writers).

But the main reason why he’s on this list is because of his battle with cancer. Remarkably, he even played on the same day as his final chemo session because he was made of something different. There’s nobody more inspiring than Lemieux because he didn’t allow his health issues to hold him back.
