Mark Cuban Gone Crazy?

"Cuban is [counter-] suing [former Mavs Coach Don] Nelson, claiming the Warriors beat the Mavs in the first round because the Warriors' coach -- and former coach of the Mavs -- had 'confidential information and he [Cuban] wants to enjoin Don from coaching against the Mavericks.'" Story. Huh? First it was the refs fault and now it's Don Nelson's? Randy Galloway had the funniest line: "If Cuban wants to sue someone over the Golden State debacle, why not Dirk?"
