This thread was an annoying read. OP is very clearly annoying but I think he did a huge disservice to himself by only putting health in the title, and OP. It got people only talking about health and ignoring everything else.
I think you'd be foolish to say the Leafs weren't lucky with good health last year. Even with the Leafs having perhaps a sports science department that helps keep up healthier by between game things as well as less TOI for players than average, and a style/players that perhaps are less injury prone it's impossible to be as healthy as the Leafs were last year without a little or a lot of luck. I don't understand how there can be 10 pages or arguing about that but here we are.
I think(but I'm not a mindreader) that OP's point was that a lot of people said things like "Oh, everything went right for the Leafs last year and they still barely made the playoffs", I'll completely concede that health went totally in our favour, I don't understand how OP can robotically argue that for days on end. But we did in fact leave a LOT of points out on the ice due to being historically awful at the shootout, and blowing an incredible amount of leads, perhaps due to inexperience. Is our own team to blame for these things instead of luck? Perhaps, I think there's a lot of luck in the shootout, but there is some skill involved for sure(as there is in injuries though), the blowing leads thing is likely on ourselves, but even with a bad team it's really tough to blow that many leads late so I would say there might be a little bit of bad luck in that as well.
I think the point was, or it should be if it isn't that while the Leafs were lucky on the injury issue last year that people did perhaps overdo it by saying everything went the Leafs way last year. Health went the Leafs way last year, and then a couple other things didn't go the Leafs way last year.
