In an offseason full of Tom Brady-to-Las-Vegas rumors, one thing is for certain: The Raiders must find upgrades at receiver and linebacker.

With two first-round picks in the 2020 NFL Draft, the Raiders can do exactly that in slightly over two months. They're sure to look at the free-agent market as well, but finding instant contributors on rookie contracts is a must for a team looking to make the leap next season.

This is especially true with the Raiders reportedly willing to offer Brady a two-year, $60 million contract.

Still, Jon Gruden and general manager Mike Mayock can shore up their two biggest positions of need right away in the draft. That's exactly what ESPN's Mel Kiper Jr. did in his latest mock draft. Kiper gave the Raiders receiver Jerry Jeudy at No. 12 and linebacker Kenneth Murray at No. 19.

The longtime draft expert explained his selections in a conference call on Wednesday.

"I have Kenneth Murray going there at 19, linebacker from Oklahoma, and have them taking Jerry Jeudy from Alabama at 12," Kiper said. "So you get the linebacker -- whether it's Murray or Patrick Queen from LSU at 19, then you get the receiver. I think it's CeeDee Lamb from Oklahoma or it's Jeudy from Alabama at No. 12."

In an ideal world for the Raiders, Clemson's do-it-all hybrid linebacker Isaiah Simmons would fall right in their lap. But Kiper said he can't see that happening without a major trade from Mayock. He has the Jacksonville Jaguars selecting Simmons with the No. 9 pick.

Josh Schrock and I, however, have Simmons going even higher at No. 4 to the New York Giants in our latest mock draft. We do agree with the positions Kiper has the Raiders targeting, but gave the Silver and Black his second options.

While Kiper has Lamb going to the New York Jets at No. 11 and Jeudy to the Raiders one pick later, we sent Lamb to Las Vegas and Jeudy being taken by the Indianapolis Colts with the next pick. The two are that close and either one would instantly boost the Raiders' receiver corps.

Murray originally wound up as a Raider in our first two editions of our mock draft, but Queen seems like he has more upside and is a better fit for the modern NFL. Murray is a fine athlete in his own regard, but Queen is much more explosive and better in coverage.

The buzz surrounding LSU's Patrick Queen is legit. He's a rangy, athletic linebacker with some impressive plays in coverage on tape. @MoveTheSticks' latest Top 50 has Queen at No. 16 (!!), and I know others are moving him up boards, as well. https://t.co/GOfsyMbxAd pic.twitter.com/PhtN3oC1sD — Austin Gayle (@PFF_AustinGayle) January 25, 2020

Queen's side-to-side range is what truly sets him apart.

Either way, the consensus is out that the Raiders likely will target receivers and linebackers in this year's draft. Any combination of Jeudy, Lamb, Murray or Queen will be huge for the Raiders' rise after a seven-win season.
