I think every team tries to reduce the number of injuries, not just the Leafs.
It would be easier to support the theory that the Leafs' low injury total last season was due to smart management and coaching if the Leafs weren't near the very top of the NHL in injuries the prior season (2015/16) with the same GM and coach.
Any reasonable assessment would conclude that injuries constrained the Jets' performance last season, and lack of injuries contributed to the Leafs' success. I don't think there is much of an evidentiary basis to project that the Jets and Leafs will have such a huge a discrepancy in injuries next season and beyond.
But not every team has the money or resources that the Leafs do. Nor, by all accounts I've seen/read, is every team putting the focus and energy into sports science the way the Leafs are. Just because every team might do a bit of due diligence on a specific element in hockey (health, advanced stats, etc) doesn't mean that every team values those specific elements the same way.
And continuing to point to a 15-16 roster that has seen the
overwhelming majority of players leaving the org (only 6-7 regulars from 15-16 are still on the Leafs) doesn't say anything about the current roster or the
recent push that Shanahan and co are making in the sports science front. The only players remaining from that roster that saw significant injuries that year are JVR & Bozak (sordid history of injuries), so again, that roster is about as irrelevant to this discussion as it gets.
I never said there would be a huge discrepancy between the injury numbers of the Leafs and Jets next year.
Again, I don't think the Leafs have discovered a magical method to prevent freak accidents. That doesn't mean there won't be
some discrepancy between the Leafs' and Jets' injury numbers. In reality, we won't be able to definitively say anything about how effective their methods are until 4-5 years from now. BUT, the Leafs' massive push (bigger than every other team in the league) in the sports science area is very recent (past year or so) and their 3 big FA signings this summer have missed a combined 84 games out of 1,162 in the last 5 years. I just think it's foolish to look at that and say the Leafs aren't doing everything possible to ensure they can ice a roster that is generally very healthy and can stay generally very healthy.
