My very rough lay understanding is that life insurance policies can be quite lucrative due to tax-free growth, and the main thing that holds back taking life insurance on arbitrary people as a general investment strategy is that you need to have some plausible reason why you're connected to someone's lifespan. I have to wonder if this whole thing isn't some giant tax dodge based on taking life insurance policies that pay a small amount to the athletes and the bulk back to whatever asset protection vehicle.
