2013 NFL Mock Draft: CBS Sports projects DT for Oakland and San Francisco

The Raiders draft at No. 3. The 49ers draft at No. 31. The Bay Area currently houses two teams heading in different directions.

The Oakland Raiders have a roster with holes from top to bottom. They'll be drafting immediate starters.

The San Francisco 49ers, on the other hand, have a roster stacked from top to bottom, and as Super Bowl runner-ups, there just isn't much they need. At this point, they'll be drafting for depth.

CBS Sports Rob Rang understands both teams' situations and projects accordingly in his latest mock draft. At No.3, Rang believes the Oakland Raiders will select Florida defensive tackle Shariff Floyd. On the selection, he says the following:

The Raiders' inability to pressure opposing quarterbacks played a huge role in their disappointing 2012 season. Oakland ranked 31st in the NFL with just 25 sacks. The 6-3, 297-pound Floyd generated 13 tackles for loss and 6.5 sacks in his first full season at defensive tackle and seems to be just scratching the surface of his potential.

Floyd tallied three sacks and 46 total tackles in his final season at Florida. He ran a 4.92 40-yard dash at the Scouting Combine.

Dan Kadar of SB Nation's Mocking the Draft agrees with Rang, as he also has the Raiders drafting Floyd, calling him, "an immediate upgrade."

For San Francisco, Rang projects the No. 31 pick to go towards defensive tackle Jesse Williams out of Alabama.

Justin Smith is expected to make a full recovery from the torn triceps which drastically limited his effectiveness late last season but he'll be entering his 13th season in the NFL. The 49ers lack much depth behind him, something the Ravens exposed during their Super Bowl victory. Williams starred this past season at nose guard for the Crimson Tide but played outside at end in their 3-4 alignment in 2011. That versatility could certainly intrigue at this point in the draft.

Williams isn't expected to be Justin Smith's replacement anytime soon, but the defensive tackle would provide valuable depth on the league's top defense.

Kadar's mock draft has a similar idea but focuses on a different position -- safety. With their first round selection, Kadar projects the 49ers to select South Carolina safety D.J. Swearinger.

The 49ers don't have a lot of needs, but could use more talent in the secondary...Swearinger would be a nice fit at free safety. He's good in coverage but can lay a hit as well.
