RG3's injury is serious -- his recovery formidable and full of uncertainty. What will his teammates do to support him? What will coaches and management do to get better? How will the culture of the organization evolve? That's where we'll learn what this team is made of.
It goes without saying that it would be a genuine tragedy if a player of RGIII's caliber were lost to injury. After all, quarterbacks as extraordinarily versatile and dangerous as Griffin don't come along very often. Or do they?
People value professional athletes based off of winning and their respect for the game that gets them paid. Robert Griffin III has shown his understanding of that, whereas Royce White has simply looked like an immature kid in a grown man's world.
Griffin's injury wasn't directly related to the controversy surrounding defenseless receivers and helmet-to-helmet hits, but it was connected to that topic. It was about the culture. Should he have played through the pain, or should he have stayed on the bench?
