If this were a case of his disks slipping, or his arm or his legs going, it'd be one thing. The weird thing about Tony's injuries is that they're bone fractures and not necessarily chronic injuries that indicate his skills are diminishing. I just have a really hard time believing a 36 year old guy's bones have suddenly gotten that much more brittle than they were in, say, 2013 or 2014. It's not like he's a 60 year old man with a low-testosterone problem.
At the same time, it's three fractured bones in two years and a couple of dozen plays overall. Maybe that's a statistical fluke, but maybe there is something else going on that we're just not thinking about. I don't know. It's easy to look at and conclude it's a problem with his body breaking down, but I'd still like to hear a little of the science that's supposedly behind it.
That said, he's missing a lot of time, and that's going to affect his level of play, too. At some point it's going to catch up.
