A fair disagreement/conversation here. And well stated by both you and Aviano.
I think Romo had one collar bone and one case of fractured ribs. You may correct me if I am mistaken.
The rest is the "back problems" which was not a skeletal issue. Once the discs go in the back. That is a whole different story and that is what kept Romo injured a few times.
Heck, Irvin career ended with a neck injury. Romo career ended with a back injury. Aikmans career ended with a back injury (I think). And Larry Birds back injury took him out of the NBA.
These players were never considered "brittle".
The spinal cord or disc injuries in a back are something you never want to mess with. I know this one all too well.
Romo had a lot of ribs problems. I think it is why he started wearing the protective gear. Off the top of my head, here are some that I recall:
1. He broke his ribs and was spitting up blood in the shower after the 2008 week 17 loss to Philadelphia.
2. As you mentioned before, he broke his ribs against San Francisco in 2011 and came back into the game.
3. It was thought he broke his ribs in week 1 against the the Giants in 2012. Some reports claimed they were bruised.
4. He claimed during the 2014 season that he played a portion of it with broken ribs but didn’t know exactly when they got broken. I remember this being a story because it was never listed in the injury report and there were concerns the team would be in trouble by the admission.
As for the collar bone, he broke that in 2010 against the Giants. He broke it twice in 2015, once against the Philly in week 2 and then on Thanksgiving against Carolina.
His back he had the slipped disc in 2013 in week 16 against the Commanders, transverse fracture in 2014 against the Commanders, and the compression fracture in 2016 preseason against the Seahawks.
Other than those he broke his finger in 2008 and missed 3 games but never had any recurring hand problems. Just a fluke hitting of a pass rushers helmet.
One note on Aikman retiring. He said many believe it was because of concussions, but it was really because he didn’t like the decisions the team made and he didn’t want to be around it any longer. This was in his Football Life episode.
