Looking at the roster, the offensive line is set, especially with the team bringing back Richie Incognito on a two-year extension. Center Rodney Hudson was inked to a long-term deal during the season, and Trent Brown and Kolton Miller look like a dominant combination at offensive tackle moving forward.
Gabe Jackson is the only real question mark on the offensive line moving forward, as he struggled through inconsistent play, and injuries in 2019. However, when healthy, he has the potential to be a Pro Bowl guard.
Running back Josh Jacobs took the NFL by storm this season, and did it with a broken shoulder for most of the season. He rushed for over 1,000 yards, and showed he can not only run around people, but also through, and fellow rookie fullback Alec Ingold was an incredible signing as a undrafted free agent.
Derek Carr will be back under center for the team in 2020 in my opinion, as I do not see Jon Gruden starting a rookie, and the free agents out there are not much of an upgrade. Despite the fan base being down on Carr, he did have the best statistical season of his career in 2019, and showed flashes of his 2016 self on numerous occasions.
The receiver corps need a major upgrade, as the whole Antonio Brown saga was a mess, and Tyrell Williams had to battle plantar fasciitis for most of the season as the presumed WR1. Rookie Hunter Renfrow was automatic in the slot, and tight end Darren Waller had a breakout season in his first full-year with the Raiders.
Las Vegas needs to add a WR1 in the first round next April, and maybe another wide receiver later in the draft, but this has all the markings of being a solid offensive unit in the first season in Sin City.
