After signing a two-year, $17.6 million deal with the Las Vegas Raiders, Marcus Mariota wants to make sure there is no quarterback controversy.

Mariota insists he's coming in as Derek Carr's backup.

"First and foremost, this is Derek's team, and I understand that," he said.

"I understand that going in. ... My priority going into free agency was to be a part of a team that I felt could bring out the best in me. Whatever happens, whatever comes of that, I'm ready for. But I do know, to play starting quarterback in the NFL, to be at that spot, is not an easy job to do. And I think when it comes down to it, a strong, stable supportive quarterback room makes that job a whole lot easier, and that's what we have to do. And I'm going to do my best to support Derek in every possible way that I can; and along with that, I'm just going to try to become the best player that I can be and see where that takes me."

The Las Vegas Raiders agreed to a two-year, $17.6 million deal with Marcus Mariota.

Mariota's deal includes $7.5 million in the first year as a fully guaranteed base salary. Mariota gets up to $2.4 million if he plays 60% of the snaps in 2020.

Mariota will serve as backup quarterback to Derek Carr.

The Las Vegas Raiders had interest in Tom Brady this week. The Raiders, however, never made a formal offer but gave him some ballpark idea of what they could pay.

The Raiders were unwilling to commit $50 million guaranteed for 2020 and 2021 to Brady.

The Raiders never reached a point where they seriously shopped Derek Carr.

Jason Witten has agreed to sign a one-year deal with the Las Vegas Raiders worth as much as $4.75 million.

Witten has spent his entire career with the Dallas Cowboys outside of his one season with ESPN.

Amari Cooper has agreed to re-sign with the Dallas Cowboys on a five-year, $100 million deal.

Cooper was acquired by the Cowboys from the then-Oakland Raiders in 2018.

Washington attempted to sign Cooper on Monday, but he ultimately decided to remain with the Cowboys.

Cooper's deal includes $60 million in guaranteed money. 

The Las Vegas Raiders have agreed to sign Marcus Mariota. 

Mike Mayock had Mariota as the top-ranked quarterback on his NFL Network draft board in 2015. 

Mariota lost his job last season to Ryan Tannehill. 

The Raiders were looking for an upgrade at quarterback behind Derek Carr.

The Green Bay Packers and Oakland Raiders are expected to be "all over" Cory Littleton once the legal tampering period opens, according to a report.

Littleton is among the potential losses the Los Angeles Rams will suffer in free agency.

Odds are that Tom Brady will return to the New England Patriots, according to American sportsbooks.

The Tennessee Titans, Las Vegas Raiders, Los Angeles Chargers and San Francisco 49ers are among the next tier of contenders on oddsboards in New Hampshire, New Jersey and Nevada.

"We're getting bets on all these teams," Jeff Sherman, vice president of risk management at the Westgate SuperBook in Las Vegas, said. "We even have a few wagers on the Vikings at 1,000-1."

The SuperBook in Las Vegas also received recent interest on the 49ers and shortened their odds from a 100-1 to 12-1.

Byron Jones is expected to hit the free agent market in a few weeks with the Dallas Cowboys focused on Dak Prescott and Amari Cooper.

According to a report, the Las Vegas Raiders will be among the teams looking to sign Jones once he becomes available.

The Raiders are also thought to have interest in Chris Harris, Jr.
