Gus Williams — a two-time All-Star for the Seattle SuperSonics — is being sued by a man who claims the ex-NBA champ didn’t pay him for a house … and trashed the place to boot.
The man behind the suit is Todd Mustin, who says back in 2017 … he put his 5-bedroom, 5,000 square-foot Sherman Oaks, Calif. pad up for sale — when things went awry.
Mustin claims he sold the house to a woman named Megan Zucaro … but when she only coughed up $1 million of the roughly $1.9 mil she agreed to pay for the place, Williams stepped in.
Mustin says the 66-year-old — who won an NBA title with the Sonics in the 1978-79 season — agreed to take over the place and pay off the remaining $900K.
The problem? Mustin says the former point guard NEVER paid a dime … and claims the guy and his family trashed the crib in the meantime.
Mustin claims Williams and his family left the place an absolute dump … telling TMZ Sports they left feces in the toilets and trash all over.
To be clear, Williams had every right to trash the place — he did buy it after all — but Mustin claims the disaster he left behind on the property proves the dude is a complete jerk.
Now, Mustin claims Williams owes him $900K — plus interest — for never paying for the house after he agreed to take it off Zucaro’s hands.
Attempts to reach Williams for comment were unsuccessful.
