The Raiders drafted five offensive linemen in the first round, with three of them being undrafted free agents.
One of them, T.J. Clemmings, is the top offensive lineman on Raiders rookie depth chart.
Two of the other three were drafted in the second round.
The Raiders selected four linemen in last week’s first round and a guard in the fourth.
The fifth draft pick, Alex Balducci, was a third-round pick in 2015 and the fifth pick, Johnnie Troutman, is a fifth-round selection this year.
The Raiders have one of the NFL’s best offensive lines, led by left tackle Donald Penn, a 6-foot-7, 335-pounder who was a first-team All-Pro last season.
The Raiders have the third-best run game in the league.
Penn was the first Raiders tackle to have a sack last season, with five sacks in 2016.
Penn’s ability to hold up on the edge will be a major asset on the offensive line, especially in the run game.
The team will likely be able to utilize the run effectively with the four new offensive linemen.
Oakland’s running game has struggled in recent years and Penn’s ability as a run blocker will help the team on the ground.
Penn was a two-time All-Pac 12 selection and one of only three tackles with at least 1,000 rushing yards in his four seasons at Stanford.
