NFL Studs and Duds: Will Levis goes crazy, Jahmyr Gibbs runs wild and Las Vegas Raiders fire McDaniels

It was a chaotic and unpredictable Week 8 for the NFL.
The Kansas City Chiefs fell flat against Sean Payton, Russell Wilson and the once-hopeless Denver Broncos.
The Dallas Cowboys again looked like serious NFC contenders with another blowout win.
Will Levis became a Sunday star, while Detroit rookie running back Jahmyr Gibbs was so good that the Las Vegas Raiders fell apart on primetime TV and Davante Adams slammed his helmet in frustration.
Head coach Josh McDaniels and general manager Dave Ziegler were then coldly fired as a Halloween treat for Raiders fans.
Here are talkSPORT’s Studs and Duds from Week 8.

THE STUDS
Will Levis, Tennessee Titans
It's hard to have a better rookie debut than Levis, who turned DeAndre Hopkins into a dominant NFL receiver again and finally gave a spark to the Titans' previously depressing season.
Ryan Tannehill isn't the future in Tennessee.
Levis is and it's time for the Titans to hand 2023 to the rookie with the arm -- and a crazy love for mayonnaise.

Jahmyr Gibbs, Detroit Lions
Another rookie, another huge breakout game.
Gibbs was perfect for the Lions on Monday Night Football, rushing for 152 yards and a touchdown as Detroit improved to 6-2.
The Lions need good luck if they're going to win big this year.
Gibbs could be the new star Detroit has been waiting for.
Bryce Young, Carolina Panthers
Speaking of rookie breakouts...
Young finally looked like a No. 1 overall pick while Carolina improved to 1-6 with a gritty win against the Houston Texans.
After all the early season talk about No.2 pick C.J. Stroud, Young was the better QB in Week 8 while Stroud regressed and only threw for 140 yards.
Dallas Cowboys
Will the real Cowboys please stand up?
Dallas has already recorded four blowout wins this year.
Philadelphia will be the real test for Dak Prescott's team in Week 9.
But when you're dropping 40 points multiple times before the midway point of the season, you're doing something right.
Denver Broncos
It still might be a lost season in Denver.
But when Russell Wilson is outplaying Patrick Mahomes, Payton still knows how to coach.
The Broncos should at least be close to .500 this year.
They shook off all their problems against the Chiefs and danced in Travis Kelce's face.
THE DUDS
Las Vegas Raiders
An early contender for the most dysfunctional NFL team of the year.
Jimmy Garoppolo is blaming himself.
Josh Jacobs has no idea how to fix the Raiders' broken offense.
Davante Adams is throwing tantrums and almost making Chad Johnson cry.
What a mess in Las Vegas.
Kansas City Chiefs
The NFL is a week-to-week league and Week 8 was a tough reminder of that fact for the Chiefs.
While Patrick Mahomes dealt with an illness, Kansas City looked vulnerable and beatable.
With one loss, the Chiefs (6-2) now find themselves tied with Miami, Jacksonville and Baltimore in the AFC.
Time to call Taylor Swift and win another game with the pop superstar celebrating in a suite.
Josh Dobbs
One week you're posting cool videos on Tik Tok.
The next you're getting replaced by a rookie QB who wasn't that great in college.
With Kyler Murray looming, the Arizona Cardinals are set to turn to Clayton Tune.
Dobbs' feel-good story has suddenly ended.
Pittsburgh Steelers
The Steelers should spend less time complaining and more time winning games.
Pittsburgh isn't scaring anyone this year.
While Jacksonville continues to impress, Mike Tomlin's team is barely above average and blaming referees.
Kirk Cousins, Minnesota Vikings
Cousins deserved better than this.
An Achilles injury cut short a strong statistical season and likely ended any hope of a Minnesota turnaround.

Now the questions will return about Cousins' future with the Vikings.
He's 35 and has already made more out of his career than was ever expected when he became Robert Griffin III's backup in Washington more than a decade ago.
