It sucks but that's the nature of the beast. Gretzky, Lemieux, Bossy, etc all lost a ton of games/points to injuries and illness. This is one of the things that makes Ovy a special player on it's own. As physical a game he plays and has only missed 29 games to date an not even all of those were to injury.
I'd add Bure to that list to. He lost both prime years and pretty much his entire peak to injuries. So many players that are still legends and we can only speculate on what could have been.
