With Jon Gruden tendering his resignation Monday amid reports of emails he sent before being hired in 2018 that contained racist, homophobic and misogynistic comments, longtime special Rich Bisaccia makes his debut as interim head coach of the Raiders, and offensive coordinator Greg Olson will be the new voice in quarterback Derek Carr’s ears, calling the plays in a matchup that pits 3-2 rivals seeking their first win in October.

Busting on free agents doesn't stop any NFL team from trying again. CORY LITTLETONThe Raiders thought they were getting a difference-maker when they signed linebacker Cory Littleton to a three-year, $35.25 million deal. STEPHEN WEATHERLYWeatherly was a major bust for the Carolina Panthers after the defensive end signed a two-year, $12 million deal last offseason.

Wentz was paid more than $39 million in cash this season and had a cap hit of $18.6 million. The Eagles now have to decide what to do with Wentz, who has a cap hit of more than $34 million next season. RB EZEKIEL ELLIOTT: The Cowboys gave Elliott a $90 million, six-year extension before reaching a deal with quarterback Dak Prescott. Elliott is coming off the least productive season of his career with 979 yards and six TDs while getting paid nearly $11 million for a team that finished 6-10. But Green had just 47 catches for 523 yards in 16 games, providing little value for his big salary.

The Las Vegas Raiders fired defensive coordinator Paul Guenther after he failed to make any significant improvement for the unit in nearly three full seasons on the job. Defensive line coach Rod Marinelli will take over on an interim basis for the rest of the season. Marinelli has previously served as a head coach in Detroit and defensive coordinator in Chicago and Dallas. He has long ties to Gruden, having served as his defensive line coach for the Super Bowl champion Tampa Bay Buccaneers in 2002 and then rejoining Gruden this season on the Raiders. We got a chance to win all three and see what happens at the end,” defensive tackle Johnathan Hankins said before the announcement.
