This was big money. Shaq and Hakeem would duke it out for a $1 million purse, furnished by Taco Bell. The two giants were at the top of the NBA at the time, but the heavyweight bout, titled “War on the Floor,” needed a slick promoter and a grand venue. It got one. Next to O’Neal and Olajuwon on the dais was the event’s host and promoter: Donald J. Trump. On Saturday, the Shaq-Hakeem basketball bout would be set for Trump’s Taj Mahal casino in Atlantic City, NJ.
