There is a name for all that, it's called "luxury problems". Like Paris Hilton telling us that her boyfriend threw her diamond thong out of the window and she can't find it anymore. Terrible.
I'll probably get downvoted for this, but somebody needs to say it: you're an a-hole.
2. Nobody is requiring anybody to read his story; he's simply making it available to anybody that is interested.
3. His story is relevant to millions of (professional, amateur, and occasional) athletes around the world... and millions more with traumatic brain injury.
4. He does have millions of dollars, but a lot of people with chronic illness would gladly trade all that money for a clean bill of health.
5. Consider that when you hear figures like "ten million dollars" that the player may receive only half of that, when taxes and agents' fees are deducted.
6. Even if he got to keep all $10mil tax-free (which he almost certainly didn't, IMO) if he lives another 50 years, that's only $120K per year. A comfortable living, well above average, but certainly not unlimited.
The $10 million he got was from an insurance policy, which he said was "tax-free", and which it sounds like he bought for himself. That agrees with what the IRS says:
"If you pay the entire cost of a health or accident insurance plan, don't include any amounts you receive for your disability as income on your tax return."[1]
And I doubt that his agent would be entitled to any of his disability insurance.
I agree with your other points.

I really, really don't see how lasting problems from brain injuries is anywhere near the same as your Paris Hilton "luxury example", except for the fact that he happens to have some money.
