Well, it's worth noting that not all NBA players are financially savvy. There have been several cases of players squandering millions of dollars in just a few years and ending up in financial trouble. So, in Simmons' case, I wouldn't be so sure he's set for life.
If he lives frugally, just like a regular employee, he is set for life. Even after taxes, agent fees, and other expenses, his take-home pay is still a lot of money.
A regular employee couldn't even earn that much in their entire lifetime, yet they still manage to survive. But if he lives lavishly, then that amount might not be enough, considering he's only 30 years old. However, if he manages his money well, he really could be set for life, with enough to provide for his future children and even his grandchildren.
How about these shoes?
That is hella funny. Lol. Kidding aside, maybe the shoe design is partly to blame, but it's definitely not the only factor.
