NFL Mock Draft 2013: Will the 49ers continue to bolster their defense in April's draft?

The San Francisco 49ers totaled 38 sacks in the regular season, and over half of those belong to outside linebacker Aldon Smith. Are Jim Harbaugh and defensive coordinator Vic Fangio going to get him some help in the first round of the 2013 NFL Draft?

Rob Rang of CBS Sports thinks so and projects that Dion Jordan of Oregon could be the answer, since he is similar to another player that the 49ers were reportedly targeting in 2012 but were not able to land:

Sources suggest that when San Francisco general manager Trent Baalke boastfully commented prior to the 2012 draft that he already knew who the 49ers would be selecting he was referring to West Virginia pass rusher Bruce Irvin. Irvin, of course, never made it to San Francisco, surprisingly earning the No. 15 overall selection by NFC West rival Seattle. The 6-5, 255-pound Jordan has a similar lanky build and natural pass rush skills as Irvin and is better in coverage.

Jordan is a 2012 finalist for the Butkus Award as the nation's top linebacker and he recorded 10.5 tackles for a loss and 5 sacks.
