Kings fans familiar with the human body, does being "injury prone" have a scientific basis?
Yes and no. In basketball, and in most sports, we're mostly talking about wear and tear on joints, and there is a genetica basis for that. Also, when one injury happens, there is a higher chance of the more injury, due to the stress on other parts to make up for the recovering joint. Derrick Rose is a good, unfortunate example. One knee gets hurt, then the other one gets hurt due to overcompensation, then the first one is hurt again.
However there are many examples of players who've had injuries early in their careers that go on to a full recovery and long careers with virtually no perceivable lingering effects.
So it's basically impossible to tell, unless a pattern emerges. But there are also a ton of things players can do to mitigate risk of injury, such as conditioning, stretching, properly warming up and cooling down, massage, structural work like chiropractic/orthopedic medicine, and even supplements to maintain the joints like MSM. MSM is huge among ranchers for feeding their horses, to keep the animals joints healthy. Ranchers don't operate on speculation. They do this because it works. All NBA players should be taking high doses of MSM. It keeps cartilage hydrated and expanded, prolonging it's finite timetable.
