Derek Carr isn’t the only Raiders quarterback who’s generating trade interest. NFL.com’s Ian Rapoport reports (via Twitter) that teams have “legitimate and real” trade interest in backup Marcus Mariota.

Mariota joined the Raiders last offseason on a two-year, $17.6MM deal. He had an IR stint in September and October, and he didn’t leave the bench until the Raiders’ Week 15 loss to the Chargers. Mariota completed 17 of his 28 pass attempts for 226 yards, one touchdown, and one interception in that game, and he added another score and 88 yards on the ground. Rapoport says that singular performance caught the eyes of other teams, with some organizations believing that Mariota could have a similar career path as Ryan Tannehill (who, of course, resuscitated his career after replacing Mariota in Tennessee).

Mariota showed glimpses of promise during his five seasons in Tennessee, but he obviously disappointed considering his second-overall-pick pedigree. The quarterback went 18-16 during his final three seasons with the Titans, but he also had only 31 touchdowns vs 25 interceptions.

We learned earlier this week that teams had inquired on Carr, and reports indicated that the Raiders were willing to listen to offers on their starting quarterback. Rapoport clarifies that while the Raiders wouldn’t hang up the phone on any team, they’re not eager to move on from the 29-year-old, and a deal for Carr would be “incredibly expensive.”

This is shaping up to be a historic offseason of quarterback movement, as Matthew Stafford has already been dealt, and Carson Wentz, Deshaun Watson, and Sam Darnold might not be too far behind. There haven’t been any concrete trade rumors regarding Raiders QB Derek Carr this year, but it sounds like that could change soon.

According to Mike Garafolo, Tom Pelissero, and Ian Rapoport of NFL.com, rival clubs have been calling the Raiders to gauge their interest in dealing Carr, and Vegas is at least willing to entertain those discussions. The caveat is that the Raiders would want to replace Carr with a passer of similar quality, though that probably would need to happen in a separate transaction. Unless Carr somehow becomes involved in a trade for Watson, no other QBs that could be on the move are as valuable as Carr at the moment.

The Raiders narrowly missed the playoffs in 2020, but that had more to do with their defense than their offense. Vegas was a top-10 unit both in terms of total offense and in points per game, and Carr set a new career-high with a 101.4 QB rating. His 4,103 passing yards were also a personal best, and he threw 27 TDs against just nine picks.

The soon-to-be 30-year-old is under contract through 2022, and his salaries in each of the last two years of his deal are just shy of $20MM, a relative bargain. So while the club would surely be able to get a terrific return if it traded Carr, its status as a potential playoff contender suggests that such a deal might not be something you want to bet your house on.

Indeed, the NFL.com trio goes on to say that the Raiders, who just handed Nathan Peterman a $1MM guarantee for 2021, are open to trading either Carr or Marcus Mariota, and it would seem that Mariota is a much likelier candidate to be moved. Perhaps there will be some discussion on that front once the dust settles on Wentz, Watson, and Darnold.

Still, the fact that the Raiders are willing to engage in talks involving Carr when they have firmly rebuffed any such overtures in the past few years is notable, especially at a time when the trade market is chock-full of interesting signal-callers.
