In a Sept. 13 brief, the league invokes its recent victory against former Las Vegas Raiders head coach Jon Gruden at the Supreme Court of Nevada to support its contention that Flores, like Gruden, must resolve disputes through an arbitration process overseen by NFL commissioner Roger Goodell before the coach can turn to federal courts.

Although the Gruden case is from another jurisdiction and is not binding precedent at the Second Circuit, the NFL believes it advances league arguments.
