@Careful you
There is a lot more to life than money. I can certainly attest to that. My argument was based only on the fact that the ESDI exists as a way of protecting the athlete in case their athletic career is jeopardized by pointing out that the protection is actually a very poor estimate of the amount of protection necessary for almost every student athlete that would be eligible to obtain the protection. The ESDI is supposed to eliminate the risk associated with a career threatening injury, but it covers maybe 25% of the likely earnings.
I look at it in the same way that someone would look at attending medical school. Yes, there is a lot of hard work, late nights, student debt, residency, etc. that goes into becoming a doctor. There are undoubtedly many that choose other professions because they don't (or can't) endure those rigors. But there are certainly non-financial benefits associated with becoming a medical doctor - prestige, lifestyle, intelligence, social status, the people you meet, etc. We can't begin to measure those.
In the same way, we can't begin to measure the change in someone's life that occurs if they lose out on a pro career due to an injury. Imagine if Jay Williams (former Duke star) has that motorcycle accident in college rather than the pros. Is he an ESPN commentator now? This isn't about the money he made as a pro. This is about rewritting not only his basketball career, but his life after basketball. That would change everything about his adult life.
And that is why the advice I would give would always be to go. A shot at the pros is a life changing event. Not just because of the money. It's life changing because of everything that comes with being a pro athlete, both the good and the bad. That's not promised, and that chance may not ever come back.
I don't know that you can compensate that at all, insurance or not.
