Shaquille O'Neal vs. Stan Van Gundy
The bad blood between Shaq and Stan Van Gundy started when both were with Miami in 2005, when Shaq criticized Van Gundy's coaching decisions following Miami's loss to the Pistons in Game 7 of the Eastern Conference Finals. The rift widened this year when Van Gundy criticized Shaq for "flopping" against Dwight Howard in a March game between the Suns and Magic. Shaq fired back, calling Van Gundy a "frontrunner," a "master of panic," and a "nobody." Apparently unaffected, Van Gundy responded: "If you're going to dish it out, you've got to be able to take it. And I can take it."
