The sports network reported that Lynch has considered coming out of retirement, and playing for his hometown team could influence his decision. According to ESPN's Adam Schefter the deal "eventually will happen". He opened his first Beast Mode apparel store there previous year.
The Raiders are in need of a running back after losing Latavius Murray to the Minnesota Vikings in free agency.
If Lynch tried to force the Seahawks into releasing him he might be able to do so simply by un-retiring and reporting for work.
Marshawn Lynch is from Oakland, attended Cal, frequently flew from Seattle to Oakland when he was a member of the Seahawks and has called Oakland his home since he retired just over a year ago. Lynch, who will turn 31 later this month, has 9,112 rushing yards and 74 rushing touchdowns in his nine-year National Football League career.
Many believed the "final hurdle" would have been Lynch making a final decision or the Seahawks giving the OK.
At the owners meeting last week, Coach Pete Carroll said Lynch had also visited the Seahawks but had not asked for reinstatement. The NFL approved the move to Las Vegas last week and the Raiders are expected to begin play there in 2020.
Lynch would be 31 when the 2017 season starts. He retired with two years left on his contract. Considering the Seahawks still hold his rights, they won't want to do that as they're looking to get something in return for letting him go.
