The 49ers and Raiders will have options in the NFL Draft, but one analyst currently projects both teams to take Defensive linemen in the first round.

The 2013 NFL Draft is deep on defensive lineman, and in his latest mock draft, Sports Illustrated's Don Banks projected both the Raiders and 49ers to select Defensive Linemen in the first round.

Banks projects Oakland to select Florida defensive tackle Sharrif Floyd with the No. 3 pick. The Raiders have lost a number of defensive linemen in free agency, and Floyd would help fill the void. He is considered to be one of the top defenders in the draft and could slide into a starting role immediately. In addition to Floyd, Banks mentions Utah Defensive Tackle Star Lotulelei as another possibility.

The 49ers have an abundance of draft picks and Banks projects San Francisco to use a few of them to trade up to the No. 18 pick and select Florida State defensive end Tank Carradine. San Francisco currently has the No. 31 pick. Carradine's stock has risen recently and the 49ers would likely need to move up in the draft if they are going to land the senior pass rusher.

In his latest mock draft for SB Nation, Matthew Fairburn also projects Oakland and San Francisco to select defensive linemen, although his picks differ from Banks. Oakland is projected to take Lotulelei with the No. 3 pick with Fairburn calling the Utah defensive tackle a more versatile prospect than Floyd.

Carradine comes off the board at No. 19 in SB Nation's mock and with the 49ers remaining at No. 31, they instead come away with Alabama defensive tackle Jesse Williams. At 6'3 and 323 pounds, Williams would give the 49ers another option at nose tackle.
