I understand your point, but what if you don't go in the first round? And you get a minimum contract? From my quick search it's $562K. I am not an insurance guy and I HATE reading riders, BUT if you get an insurance policy for $5m and you blow your knee on the first game, then I doubt the insurer will be writing you a check for $5m, The insurance company would argue that the kid would have never gotten to a $5m contract.
It is sort of like getting a piece of jewelry insured. You get an appraisal on a ring for $5k, insure it for $5k, and then you lose it. The insurance company comes back and says...I can replace that for $2.5k, here you go (my wife and I had this happen). The insurance policy is not a guarantee of the amount of coverage, just that you are covered.
Also --> sorry for the sidetrack.
Well, there are apparently also insurance policies against dropping stock in the draft, not just for injuries that are career enders. See the post from Old as Dirt above, referencing Fournette's policies: "he has another policy for 10 million that covers him for circumstances that would lead him from falling from his projected NFL draft position."
So, if Harry's stock dropped and he ended up making less but still signing an NBA contract then he could have insurance that would cover that difference in earnings as well.
I'm not sure what you mean "blow your knee in the first game." Of his sophomore year at Duke? Then yes, that is exactly the kind of thing where the policy should pay in full. If you mean his first year in the NBA, then no, the policy would expire when he arrived at the NBA - it covered his pre-NBA time. So, the policy wouldn't help him in that case.
I definitely don't understand the specifics of how much Harry would get paid if he got both types of insurance (including the one for draft stock falling), signed a contract for $562k, and then got hurt his first game in the NBA, and never signed another NBA contract. But I imagine that's all worked out at the time of signing. If they project Harry as the #20 pick, then I would assume the insurance policy that covers draft stock falling would pay him the difference between what he would have made in that first contract as a #20 pick as compared to what he made signing that $562k contract. And that the parties would have worked all of that out explicitly at the time they entered into a contract.
So, at #20, Harry would get $1.30M for year 1 and $1.36M for year two. That's guaranteed salary of $2.66M
Now, pretend instead of leaving now as the projected #20 pick, he instead stays another year, performs poorly or gets hurt again, and ultimately signs for $562k and only one guaranteed year. He then suffers a career ending injury his first game in the NBA, I assume the policy should pay out $2.66M - $562k = $2.098M
Now, if he had suffered a career-ending injury while still at Duke, he should get paid the full $2.66M
I have never seen one of those policies, though. Maybe they only pay 80% of the net or 90% of the net.
