You make light of it...but Romo literally got hurt...in the first quarter, of the first pre-season game, on the first offensive drive...on the first passing play...
So the chances of Romo getting hurt in his first game back was better than average...
Was I being sarcastic? Yes. I usually am. And you are also correct describing when Romo was injured that preseason.
However there is both an incomplete and premature assumption made by you. The former is not stated but nonetheless assumed. It is more likely Romo's injury occurred to positioning of his body during his slide and the path of the directed force taken through his body into the ground. A logical conclusion suggests the tackle and the resulting injury was more a physics related causation and less an after-effect of a physiological deficit, for example, lower than normal bone density. Rationalization is the reason why 'I make light' of some individuals' unwavering belief all of Romo's injuries--or any athlete automatically labeled as 'injury-prone'--are due to him or they as being 'made of tissue'. lol.
The latter is the interconnected assumption of a sustained injury automatically predicted being a precursor of future injury. While there is no logical way of predetermining how or when all injuries occur, it is a common human trait to predict a future event based on either observed prior situations or postulated cause-and-effect. In short, some people guess and 'know' they are and will be right. How and why actual circumstances transpire are dismissed as trivial or nothing at all.
Even though I voluntarily and repeatedly rehash an analytical viewpoint, I understand the past is the past. The time for testing who was 'right' and who was 'wrong' was extinguished a long time ago by the only true decision makers for roster assignments, who are Jason Garrett and (primarily in my opinion) Jerry Jones. My sarcasm extended to both gentlemen for the directive taken in the 2016 postseason regarding the quarterback position when I 'thanked' them.
