The Oklahoma City Thunder have crossed their I's and dotted their T's. They have signed Jalen Williams to a five-year, $287 million contract extension that'll keep him in OKC through the 2030-31 season. There are some incentives involved, but it's the most money the 24-year-old could've gotten.

Jalen Williams played a key role in the OKC Thunder's championship run last season despite dealing with a wrist injury.

Williams has agreed to a five-year maximum rookie extension that could reach $287 million, according to ESPN. This OKC "big three" is now locked in with the Thunder for multiple years and could account for as much as $822 million on the payroll.
