About to be an overnight MILLIONAIRE? Great. Pay attention.
Don't be a dumbass and blow your fortune like Antoine Walker ... be smart like Kawhi Leonard ... so says NBA veteran Wilson Chandler.
WC was a 1st round pick in 2007 and knows exactly what it's like to be a young guy with crazy disposable income.
So, we asked him to give a message for the hoop stars in Thursday's NBA Draft -- and dude dropped some valuable knowledge.
As for Antoine Walker -- he's not embarrassed about blowing $110 MILLION ... but he doesn't want anyone else making the same mistake.
