Pretty sure there's an element of every fanbase that thinks 'we have it worse than every other team in the NFL'.
My own take is that it feels like injuries have gone up all over the league since the new practice rules were implemented with the last CBA. I will say that's just a feeling though. I haven't done the research to back it up.
I do that that at some point you'll see someone in the media - or maybe even the league itself - investigate that question.
I have heard several analysts / former players speculating that exact same thing and I think you are on to something. Like you, I haven't seen any research to back that up but it does seem like that is the case.
