IMO there are certain types of injuries that repeat more than others. But I think in many of those it's more about poor recovery from the first injury (coming back too soon) and/or poor rehab and training habits that make those injuries more likely to repeat.
Poor recovery/poor rehab is self-explanatory. I think you classic example of poor training habits in a guy like Davante Parker. He had notoriously poor nutrition and training habits and seemed to be perpetually injured. Players learning better habits alone would remove the injury prone label from many players.
Another factor is the ability to play well through injury. Tua had injuries but missed few games in college. He was held out by Flores for a "finger" injury, but it was well documented that he could play. It was clearly a retaliation by Flores for Tua telling the press he was ready to play. Even the concussions were over-blown due to media. He was held out ridiculously long compared to most. Guys like Burrow have admitted to having multiple concussions and not being held out. As a result, the "injury prone" marker gets applied more to a guy like Tua than say a guy like Lamar Jackson or Burrow. They may have had just as many injuries but circumstances were different.
Finally, I would mention play style as a factor. Repeated studies have shown that smaller players at most positions get hurt less in the NFL. That's not b/c they're tougher. It's b/c they take fewer hits and fewer full force hits. All of the injuries Tua had last year were due to play style. He could have easily avoided all of them by getting rid of the ball faster/playing smarter. Part of that will happen organically just by being in the same system another year, but Tua consciously avoiding hero ball will make a huge difference. That doesn't mean to "play scared". It means to know when to take the risk and when to wait for the next play or drive.
Many people are quick to just make the assumption that Tua will miss time based on history, but IMO that's simplistic and ignorant of the facts of that history.
