On Tuesday, the Las Vegas Raiders set their initial 53-man roster, giving us insight into what Head Coach Jon Gruden and General Manager Mike Mayock were seeing and thinking throughout Training Camp.

The roster features a mix of veterans, young draft picks and a few surprises. Let's take a look at how this Raiders roster was compiled.

NFL Draft (22 players)

All but one of the Raiders' 2021 draft picks made it to the initial roster after many of them showed out during the preseason. The Raiders have built up a strong foundation on their previous picks and hope to see continued growth among not only their newest additions, but also the growth of last year's draft class which endured an unprecedented football season amid the pandemic.

Derek Carr remains as the sole longest tenured draft pick, now entering his eighth season with the Silver and Black.

Trade (1 player)

The Raiders acquired Jones from the Buffalo Bills in 2019. Jones has established himself well among the wide receivers and accumulated 62 receiving yards on four receptions over the course of the two preseason games he played. The receiver said he is striving to become a jack-of-all-trades on the offense, which was on display when he lined up at wideout and the slot receiver role throughout camp.

Free Agency (20 players)

*signed off waivers in 2018

The Raiders picked up a lot of big names in free agency this past offseason, including Kenyan Drake, Casey Hayward Jr., Gerald McCoy and Yannick Ngakoue. Most of the acquisitions were aimed at improving the defensive side of the ball, where the Raiders have struggled most in the past few seasons. Ngakoue is poised to help lead the D-line, while Hayward will anchor the DB room to get them familiar with the Gus Bradley defense he knows well.

Undrafted Free Agents (9 players)

The Silver and Black haven't had an rookie undrafted free agent make the initial roster since 2019, when four UDFAs — all of whom are still on the team — ultimately made it on. Bowers is the newest addition to this group, after spending the entire 2020 season on the Raiders' practice squad and showcasing his potential throughout camp. The tight end made a case to earn his spot after a 16-yard touchdown in the last preseason game.
