Zion Williamson is SO good … a shoe company could sign the guy to a $100 MILLION contract when he leaves Duke — so says Jay Williams.
TMZ Sports spoke with the Blue Devils legend out in NYC when he told us Zion is so insanely talented, he should get the biggest sneaker contract since LeBron James.
"He has that marketability. That smile. And, who else is 6'7", 285 with a 43-inch vertical that can entertain you like that? Nobody."
Of course, LBJ famously signed a 7-year, $90 million Nike contract back in 2003 before he entered the NBA. But, most guys coming out since haven't come close to those figures.
In fact, DeAndre Ayton's deal with Puma last year was worth just a reported "multi-million dollars."
Translation … NOWHERE near 9 figures.
