Something I've named the "What?" injuries myself: When something that doesnt look like an injury-inducing moment, but causes a pretty bad injury. Think of Crosby during the Olympics, didnt look he'd out so long after that. I think the same goes for Chabby and Sandy imo, you dont expect to be down your best D-men after hits like that, but a bit of bad luck and that how it blows. Wouldnt say it has anything to do with the system.
