Prayers & best wishes to Paul George!
Heaven forbids anyone (not just pro athletes) breaks a single bone, let alone two.
But if you wanted to choose a break, that would have been the type of break you would have wanted to choose. Clean, quick and complete break on both lower extremety bones.
The type of bone breaks you don't want, are the breaks that are not clean, not complete through. These are the breaks where the bone is completely "shattered" and the bones are not just broken, but "pulverized". Where the bone damage isn't resulted into pieces of bone, but dust or powder.
No amount of surgery can effectively repair shattered bone, dust/powder bone. Time & individual self healing abilities will have more say.
