The same can be said because Mario’s hardship occurred in 92-93 and he never again had a recurrence thankfully. Orr had serious knee issues his entire career.
Lemieux had issues with his back dating back from juniors. He's always had to deal with major health issues, and to that you add the cancer. While Orr had bad knees, he didn't have guys hanging onto him to go for a ride like Lemieux often did. I don't think you realize in how terrible shape Lemieux was...there was a point where he couldn't even tie his own skates, he'd still go out and dominate.
The Pens even cuztomised his own stall so he'd be more comfortable sitting down and giving room for trainers to tie him up. The Dr. there even recalls how they would help him stand up and give him a little push to get him moving.
You should watch Lemieux documentaries, they give some good insight into just how bad it was for him.
It's not comparable.
