A second-round pick by the Texans back in 2016, Martin spent last season with the Raiders. He will offer depth after the Commanders lost Chase Roullier to a knee injury. Roullier was placed on injured reserve in a corresponding move. 

A starter the past four years in Houston, Martin was released on the eve of free agency. He slots in as the immediate favorite to replace Rodney Hudson in Las Vegas, though the Raiders undoubtedly have more bodies to add on the interior. Martin can hold his own in the passing game but tended to get washed out in the run. That is not going to fly with coach Jon Gruden, but perhaps Martin's blocking will improve in a different system. 

Houston's former second-round pick in 2016, Martin, the younger brother of Cowboys G Zack Martin, was signed to a three-year, $33 million contract two years ago that included $18.3 million guaranteed. The Texans will ultimately save $6.25 million against the cap by moving on, simultaneously losing its starting center in every game for the past three seasons. Martin, 27, is notably an above-average pass blocker but struggles creating holes in the running game. The organization could instead opt to shift starting right guard Zach Fulton to center moving forward.

Martin came into the 2019 season on the final year of his rookie deal. The 26-year-old started in 30 games for Houston over the last two seasons.
