It's an interesting subject that most of us have no qualifications to comment on. Anecdotally, yeah, when a team is among the most-injured year after year there could be something wrong with the formula. At some point it stop being bad luck.
Either way, the Habs should hire experts who can confirm what is – or isn't – going on.
I think that it benefits from a stats-based, biomechanics-infused, hockey-savvy approach, which is conducive to on-ice success. Even a low-tech, data-intensive method is better than what is done now.
For example, look at players like Suzuki who are durable, on game film, and zoom in on what they do to avoid serious injury in the most dangerous collisions. Do this for the top 30-40 ironman players, and then do a study in contrast with oft-injured players, in similar scenarios. I bet that a biomechanics-trained hockey analyst will spot systematic differences in the response to these plays. A high tech approach would involve neural networks-based human pose estimation that could actually feed into biomechanical simulations, but that could come later.
Go back to that latest Dach injury due to the hit by Tinordi. Would Suzuki or any of the other ironmen been impacted similarly? I bet not, though I don't know for sure. This needs a combination of hockey knowledge and biomechanics to define what the ironmen do better.
Also, look at training practices of these ironmen. Do they emphasize specific strength training for vulnerable areas? Do they work flexibility training more or differently? Yoga? Preventative PT? Maybe look at other sports. A guy like Djokovic took almost two decades of pounding on tennis courts, with few injuries till recently.
That would be the job, for the right candidate.
