Hope he manages it by himself. The payout for a 280mil win is maybe 100mil after taxes. If he puts it in a savings account he is still set for life. Where lottery winners and sports stars get in trouble is from all the hangers-on who start to leech off them and push them into 'investments' and tax dodges. Oh, and spending like a billionaire of course, eg on 'someone who flies them around'.
But that's not limited to young people either. I had a neighbor who inherited 15mil including a 100 acre estate on the Potomac but in the end wasn't able to pay her electrical bill. NYC attorneys and financial advisors will bleed you dry in a few short decades.
